Java Datatypes

Java has 8 primitive data types; char, boolean, byte, short, int, long, float, and double. For this exercise, we'll work with the primitives used to hold integer values (byte, short, int, and long):

A byte is an 8-bit signed integer.

A short is a 16-bit signed integer.

An int is a 32-bit signed integer.

A long is a 64-bit signed integer.

Given an input integer, you must determine which primitive data types are capable of properly storing that input.

To get you started, a portion of the solution is provided for you in the editor.

Input Format

The first line contains an integer, T, denoting the number of test cases.

Each test case, T , is comprised of a single line with an integer, Datatype , which can be arbitrarily large or small.

Output Format

For each input variable and appropriate primitive, you must determine if the given primitives are capable of storing it. If yes, then print:

n can be fitted in:

* dataType

If there is more than one appropriate data type, print each one on its own line and order them by size (i.e.: ).

byte<short<int<long

If the number cannot be stored in one of the four aforementioned primitives print the line:

n can't be fitted anywhere.

Solution:

import java.util.*;
import java.io.*;



class Solution{
    public static void main(String []argh)
    {



        Scanner sc = new Scanner(System.in);
        int t=sc.nextInt();

        for(int i=0;i<t;i++)
        {

            try
            {
                long x=sc.nextLong();
                System.out.println(x+" can be fitted in:");
                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");
                //Complete the code
            }
            catch(Exception e)
            {
                System.out.println(sc.next()+" can't be fitted anywhere.");
            }

        }
    }
