# Java: Program to start with an integer n, divide n by 2 if n is even or multiply by 3 and add 1 if n is odd, repeat the process until n = 1

## Java Basic: Exercise-86 with Solution

Write a Java program starting with an integer n, divide it by 2 if it is even, or multiply it by 3 and add 1 if it is odd. Repeat the process until n = 1.

**Sample Solution:**

**Java Code:**

```
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
// Prompt the user to input the value of n
System.out.println("Input the value of n: ");
// Create a Scanner object to read user input
Scanner in = new Scanner(System.in);
// Read an integer from the user
int n = in.nextInt();
// Continue looping until n becomes 1
while (n != 1) {
// Check if n is even
if (n % 2 == 0) {
n = n / 2; // If even, divide n by 2
} else {
n = (3 * n + 1) / 2; // If odd, perform a calculation
}
}
// Print the final value of n
System.out.println("\nValue of n = " + n);
// Close the Scanner
in.close();
}
}
```

If input 5

Sample Output:

Input the value of n: 9 Value of n = 1
