If you want to know which version of Java that you are using by code at runtime, you can do that by using the Java System property java.version. Let's see a code example,
package org.code2care.javaexamples;
/**
*
* How to know the Java Version
* using Java system property
* java.version
*
*
* @author code2care
*
*/
public class JavaVersionExample {
public static void main(String[] args) {
String javaVersion = getJavaVersion();
System.out.println(javaVersion);
}
public static String getJavaVersion() {
return System.getProperty("java.version");
}
}
Output: 15.02
