help me the code error

Question

class datatype3{
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 \n* short \n* int \n* long");
else if(x >= -32768 && x<= 32767)
System.out.println("* short \n* int \n* long");
else if(x >= - 2147483648 && x<= 2147483647)
System.out.println("* int \n* long");
else if(x >= -9223372036854775808 && x<= 9223372036854775807 )
System.out.println("* long");
}
catch(Exception e)
{System.out.println(sc.next()+" can't be fitted anywhere."); }

}
}
}

try
{
long x=sc.nextLong();
System.out.println(x+" can be fitted in:");
if(x>=-128 && x<=127)System.out.println("* byte \n* short \n* int \n* long");
else if(x >= -32768 && X<= 32767)
System.out.println("* short \n* int \n* long");
else if(x >= - 2,147,483,648 && x<= 2,147,483,647)
System.out.println("* int \n* long");
else if(x >= -Math.pow(2, 63) && x <= Math.pow(2, 63) - 1)
System.out.println("* long");
}

/* IF the last conditional is changed....this code snippet works well.........how is this possible
