Java Datatypes

    That messed me up. I casted and was not able to get the as long value. Once I remove it worked.

      We do not need to cast explicitly. We are just required to check the applicable ranges.

      if(x>=-128 && x<=127)
	System.out.println("* byte");
if(x>=-(Math.pow(2,15)) && x<=(Math.pow(2,15)-1))
	System.out.println("* short");
if(x>=-(Math.pow(2,31)) && x<=(Math.pow(2,31)-1))
	System.out.println("* int");
if(x>=-(Math.pow(2,63)) && x<=(Math.pow(2,63)-1))
	System.out.println("* long");

      Casting is necessary because Math.pow function returns value in double
