How to print the value of variable in java

If System.out.printf is giving you this error:

 The method printf(String, Object[]) in the type PrintStream is not applicable for the arguments (String, int)

Then you must configure your project for the proper Java version.

Methods with variable arguments were introduced with Java 5.

Alternatively, you could do:

System.out.printf(The Sum of %d and %d is %dn, new Object[] {a, b, sum});

Alternatively you can use .format

System.out.format(The sum of %d and %d  is %d .  ,1, 2, 3);

With proper Java version set .printf also works as expected

System.out.printf(The sum of %d and %d  is %d .  ,1, 2, 3);

 int a = 2;
 int b = 4;
 int c = a + b;
 System.out.format(The sum of %d  and  %d is %d , a, b, c);

This is simple way in the formatted output
