    This is the solution for all the testcases

    import java.io.*;
import java.util.*;
import java.math.*;

public class Solution {

    public static void main(String[] args) {
        /* Enter your code here. Read input from STDIN. Print output to STDOUT. Your class should be named Solution. */
        
        Scanner sc = new Scanner(System.in);
        int count = Integer.parseInt(sc.nextLine());
        
        for(int i = 0; i < count;i++){
            String strNum = sc.nextLine();
            BigInteger bigNum = new BigInteger(strNum);
           
            
            if ((bigNum.compareTo(BigInteger.ZERO) > 0  && bigNum.compareTo(BigInteger.valueOf( Long.MAX_VALUE )) > 0) || (bigNum.compareTo(BigInteger.ZERO) < 0  && bigNum.compareTo(BigInteger.valueOf( Long.MIN_VALUE )) < 0)){
                System.out.println(bigNum + " can't be fitted anywhere.");
            } else
                System.out.println( bigNum + " can be fitted in:");
            
            if (bigNum.compareTo(BigInteger.valueOf(Byte.MAX_VALUE )) <= 0 && bigNum.compareTo(BigInteger.valueOf(Byte.MIN_VALUE )) >= 0){
                System.out.println("* byte");
            }
            if (bigNum.compareTo(BigInteger.valueOf(Short.MAX_VALUE )) <= 0 && bigNum.compareTo(BigInteger.valueOf(Short.MIN_VALUE )) >= 0){
                System.out.println("* short");
            }
            if (bigNum.compareTo(BigInteger.valueOf(Integer.MAX_VALUE )) <= 0 && bigNum.compareTo(BigInteger.valueOf(Integer.MIN_VALUE )) >= 0){
                System.out.println("* int");
            }
            if (bigNum.compareTo(BigInteger.valueOf(Long.MAX_VALUE )) <= 0 && bigNum.compareTo(BigInteger.valueOf(Long.MIN_VALUE )) >= 0) {
                System.out.println("* long");
            }
        }
    }
}

    Why is this wrong, when it gives the exact output as the expected? 

    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>=-32768 && x<=32767)System.out.println("*short");
                if(x>=-2147483648 && x<=2147483647)System.out.println("*int");
               System.out.println("* long");
            }
            catch(Exception e)
            {
                System.out.println(sc.next()+" can't be fitted anywhere.");
            }

        }
    }
}

    guys testcases 2/4 is passed remaing two is failed give me the solution

    The sample solution has you looking up the values of the min and max numbers. Much better to use the static fields

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

            try
            {
                long x=sc.nextLong();
                System.out.println(x+" can be fitted in:");
                if(x>=Byte.MIN_VALUE && x<=Byte.MAX_VALUE)System.out.println("* byte");
                if(x>=Short.MIN_VALUE && x<=Short.MAX_VALUE)System.out.println("* short");
                if(x>=Integer.MIN_VALUE && x<=Integer.MAX_VALUE)System.out.println("* int");
                if(x>=Long.MIN_VALUE && x<=Long.MAX_VALUE)System.out.println("* long");
            }
            catch(Exception e)
            {
                System.out.println(sc.next()+" can't be fitted anywhere.");
            }

        }
