﻿ Java - Test if 2 numbers have the same digit between 2 values

# Java: Accepts two integer values between 25 to 75 and return true if there is a common digit in both numbers

## Java Basic: Exercise-64 with Solution

Write a Java program that accepts two integer values between 25 and 75 and returns true if there is a common digit in both numbers.

Sample Solution:

Java Code:

``````import java.util.*;

public class Exercise64 {
public static void main(String[] args) {
// Create a Scanner object for user input
Scanner in = new Scanner(System.in);

// Prompt the user to input the first number
System.out.print("Input the first number : ");
int a = in.nextInt();  // Read and store the first number

// Prompt the user to input the second number
System.out.print("Input the second number: ");
int b = in.nextInt();  // Read and store the second number

// Call the common_digit method with the two numbers and print the result
System.out.println("Result: " + common_digit(a, b));
}

// Define a method to check if there's a common digit between two numbers
public static boolean common_digit(int p, int q) {
// Check if p is less than 25 or q is greater than 75
if (p < 25 || q > 75) {
return false;
}

// Extract the last digit of each number
int x = p % 10;
int y = q % 10;

// Remove the last digit from both numbers
p /= 10;
q /= 10;

// Check if there's a common digit by comparing the remaining digits
return (p == q || p == y || x == q || x == y);
}
}
```
```

Sample Output:

```Input the first number : 35
Input the second number: 45
Result: true
```
