Help me out with this code, i dont know why the error happens only if the entered number suits only long datatype...kindly please do help me out to solve this code.

import java.util.*; public class datatype{ public static void main(String[] args){ Scanner pr=new Scanner(System.in); int t=pr.nextInt(); int count=0; String a[]=new String[t]; for(int i=0;i

        try {
            long a1=Long.parseLong(a[j]);
        if(-9223372036854775808l<=a1 && a1<=9223372036854775807l){
            count=1;
            System.out.println(a[j]+" can be fitted in:");
            int b=Integer.parseInt(a[j]);
        if(-128<=b && b<=127){
               System.out.println("* byte");
        }
        int  c=Integer.parseInt(a[j]);
        if(-32768<=c && c<=32767){
            System.out.println("* short");
        }
        int d=Integer.parseInt(a[j]);
        if( -2147483648<=d && d<=2147483647){
            System.out.println("* int");
        }
            System.out.println("* long");
        }
        } catch (Exception e) {
            // TODO: handle exception
            if(count==0){
            System.out.println(a[j]+" can't be fitted anywhere.");
            }
        }
        count=0;

    }
    pr.close();
}

}
