public class Test {
    public static void main(String[] args) {    
            Integer a = 1000, b = 1000;  
            System.out.println(a == b);
            Integer c = 100, d = 100;  
            System.out.println(c == d); 
    }
}

Answer 1

javac will compile the file, you need to run it by java Test

Executing javac will only create the compiled bytecode file, named Test.class

Answer 2

To compile and run your class Test.java you should do this.

javac Test.java --to compile

and

java Test  -- to run

you can take a look at this link

Answer 3

The javac command in Java compiles a program from a command prompt.

javac Test.java

Since nothing is printed to the terminal, we will assume it did not have any errors.

The java command from a command prompt runs the program.

java Test
