Java Datatypes

  • amitrajitbose9 + 3 comments

    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");

      i tried using appying the range directly but i couldnt able to clear two test cases

        which?

        • barathvicky + 2 comments

          u added pow function but i tried with entering the range values like for byte -128 to 127 but i am not able to clear the 2 testcases among 4

            same here, could u help.

            you will not be able to clear the test cases if u use that method because th range of because the range of int and long are very large to be inputted xplicitly like if u enter 2147483648 which is the rangeof int is verylarge value for compiler

              I meant something like Byte.Max() which does not require any literal number to be input but will always be dependant on the compiler...

        You must have used if(x>=-Math.pow(2,31) && x=-Math.pow(2,31) && x<= Math.pow(2,31)-1 ) and also for long ""x<=Math.pow(2,63)-1""
