Java Control Statements

Java 11 onwards, now a single java file can be tested easily without compiling as well. Consider the following example −

ApiTester.java

public class Tester {
   public static void main(String[] args) {
     System.out.println("Hello World!"); 
   }
}

$ javac ApiTester.java
$ java Tester
Hello World!

$ java ApiTester.java
Hello World!

This new feature will help developer to quick test a functionality without need to compile before running a code.
