Know the Java version using Java Code


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
