Sorry, I'm new to Java (but I've learn C++ before so Java seems to be familiar)
I facing this problem as shown in Figure below
I want to divide the two values but it seem something goes wrong (without error)
but if I change the sign to "+" or "*" , they seem to perform perfectly.
Can anyone tells me whats wrong with the "/"?
By the way, there's a light bulb beside it saying that Resource leak, may I know what's wrong as well?
One more question, I've tried another method using

public class PrintSquare {
public static void main(String[] args) {
int userInput; 
int square; 
System.out.print("Please type a number: ");
userInput = TextIO.getlnInt();
square = userInput * userInput;
System.out.print("The square of that number is ");
System.out.println(square);
}
}

Everything seems fine except for the line userInput = TextIO.getlnInt();
The error says that TextIO can't be resolved.
May I know what's problem with it as well?

Sorry I have problem uploading photos so I guess I have to copy paste all code

import java.util.Scanner;
public class PrintSquare {
   public static void main(String[] args) {
      Scanner s = new Scanner(System.in);
      System.out.print("Enter first number: ");
      int firstNumber = s.nextInt();
      System.out.print("Enter second number: ");
      int secondNumber = s.nextInt();
      int sum = firstNumber * firstNumber;
      int sum2 = secondNumber *secondNumber;
      int sum3 = sum/sum2;
      System.out.println("The result is " + sum3);
   }
} 

Output:
Enter first number: 5
Enter second number: 9
The result is 0

Sorry I forget to mention that I'm using Eclipse IDE

Sorry Case Closed Found the reason behind already

In case it isn't obvious, you're doing integer division, which will lose anything after the decimal point. You therefore need to make one of the operands a floating point value.

Also, when posting code here, please put it within code tags - see the text in the box where you type your post, as it tells you what to do.
