What is Java?
Any operating system that handles the Java Virtual Machine (JVM) may run Java programs thanks to the popular object-oriented programming language and software platform known as Java. First launched by Sun Microsystems in 1995, it is famous for its “write once, run anywhere” capability, which makes it a favorite. possibility for developing several uses, including corporate software, Android apps, and web apps.
The key feature of Java that sets it apart from many other technologies is its architecture, which allows code written in Java to execute on any device that can support a Java virtual machine (JVM). The phrase “write once, run anywhere” was used to highlight Java’s cross-platform app compatibility.
Because Java environments are available on a wide range of devices, both big and small, a Java developer has greater freedom to approach code as independent of the system it runs on.
Java is an object-oriented programming language that shares syntactic similarities with C++. Java applications are always object-oriented, in contrast to several other languages that came before it that implemented classes but did not necessitate their use. Therefore, it is better to know is Java safe or not in 2025.
Is Java Dead in 2025?
A platform that supports several programming languages is Java. When Java was first launched in 1995, its practical multimedia and interaction made it a good fit for the web. Because Java has been around longer than most other languages, it still enjoys an advantage over its rivals. Java is still a commonly used programming language, despite the fact that it might not be appropriate for every situation. However, there are a number of issues that cast doubt on Java programming’s future.
The primary factor contributing to Java’s immense popularity is its creators’ constant upgrading of the program to meet the demands of emerging technological trends. On March 16, 2021, Java’s most recent version, JDK 16, was made available.
Machine learning libraries are abundant in Java. Java is still a good choice for creating enterprise-level applications, cloud computing, and Android apps as well. Technological giants like Google, Amazon, and Netflix continue to employ Java to build secure and scalable systems. It is difficult for new languages to fully replace it because of its extensive libraries, significant community support, and cross-platform features. Because of its versatility and extensive usage in contemporary software projects, the answer to the question of whether Java is still relevant in 2025 swings toward the affirmative.
Even if Python, Kotlin, and Go are becoming more popular, Java programming appears to have a bright future as it develops new capabilities. Java will continue to be very relevant in the years to come as long as companies need reliable, portable, and secure solutions. Let’s understand is Java safe or not in 2025.

Is Java Safe to Use in 2025?
Indeed, Java server and desktop apps are generally safe.
You grant desktop applications, such as Skype, Picassa, and others, complete access to your computer when you launch them. You must have to trust the program.
On the other hand, a Java applet operates in a sandbox, which is a limited environment, when it is executed within your web browser. You don’t have to rely on the Java applet because of the sandbox.
The majority of Java’s vulnerabilities are “sandbox escapes” in nature. In other words, a malicious applet can escape the sandbox and take over your machine if you’re using an outdated version of Java.
Many technologies do not support sandboxes. Actually, just three major technologies—Java, JavaScript, and Flash—are frequently used by individuals to execute untrusted applications. The complexity of creating a safe sandbox demonstrates the numerous sandbox escape vulnerabilities found in each of them.
Running Java on a desktop or server eliminates the need for the sandbox since you can trust the Java code. The primary worry in that situation is whether unreliable data may hamper the application. For instance, if you’re on Skype with someone, they may send you a malicious message that Skype mishandles and gives them access to your computer.
What Are The Top 5 Java Security Flaws?
After knowing whether is java safe or not, here are the top 5 Java security holes in 2025:
JUnit
Quick and automatic codebase testing is made possible by this unit testing framework, which is a typical component of most Java developers’ toolkits. JUnit files used with other programs, however, may include security flaws. For instance, the Google Web Toolkit (GWT) has many cross-site scripting (XSS) vulnerabilities in versions before 2.5.1 RC.
The Jenkins
Jenkins has a sizable following among Java developers as the most widely used continuous integration (CI) server available. There are several XSS, cross-site request forgery (CSRF), and denial-of-service (DoS) vulnerabilities in Jenkins, which is unfortunate because widespread use of the continuous integration tool typically results in additional vulnerabilities and attacks.
Hibernate
Java developers frequently utilize the famous ORM framework Hibernate to map relational database objects, such as tables, to Java classes. The open source utility has a flaw in versions 4.1.0 before 4.2.1, 4.3.x before 4.3.2, and 5.x before 5.1.2 that can let attackers get around the Java Security Manager (JSM).
Maven
A popular build manager for Java projects, Nginx or Apache Maven enables the central administration of a project’s documentation, reporting, and build. A man-in-the-middle attack vulnerability in Apache Maven 3.0.4 enables remote hackers to impersonate servers.
The Tomcat
Developers have long favored this well-known Java web application server for creating servlets and JavaServer Pages applications. Since Tomcat has been around for more than ten years, it has accumulated a rather amazing number of security flaws, ranging from CSRF to XSS vulnerabilities, many of which have been used in the wild. Therefore, due to these Java security holes, it is difficult to understand whether is Java safe or not.
Java’s Use in Modern Technologies
Java is still important in cutting-edge IT industries. It drives essential cloud, AI, and data processing technologies and frameworks.
Big Data and Machine Learning
Machine learning and big data both heavily rely on Java. Several popular data tools use Java.
Java powers the popular big data platform Apache Hadoop. This enables it to function on a wide range of computer types. Java additionally functions with Apache Spark, another one of the best big data tools.
Spark facilitates the quick processing of massive volumes of data and performs well in machine learning applications.
Machine learning gets help from Java libraries such as Deeplearning4j and Weka. They handle intricate math and data processing, making the development of intelligent systems simple.
Architecture For Microservices And Cloud-Native Solutions
Java works nicely with contemporary cloud computing platforms. Building microservices—small, targeted components of larger apps—is an excellent use case for it.
Several cloud systems support Java. Java programs may operate easily in the cloud thanks to Amazon Web Services (AWS) specialized technologies.
A Java framework called Spring Boot aids in the development of cloud-ready applications. It enables developers to quickly create microservices that can scale up or down in response to demand.
Because of its security capabilities, Java is also a strong choice for cloud computing. Java is still a popular choice for cloud projects by banks and other corporations because it helps protect data when programs operate on shared computers. So, is Java safe or not, and what is the future of it in 2025? Let’s find out.
