Question

Actually my system gives Long.MAX_VALUE as 9223372036854775807

But when I write my program like this,

package hex;

/**
 *
 * @author Ravi
 */
public class Main {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        // TODO code application logic here

        long x = 9223372036854775807;

        System.out.println(x);

    }

}

I am getting compile time error. Can anyone explain the reason?

Answer 1

With no suffix, it’s an int constant (and it overflows), not a long constant. Stick an L on the end.
