Java for loop find all number combinations

Question

We would like to write a program that displays all possible combinations for picking two numbers from integers 1 to 7.

Also display the total number of all combinations. 

public class Main {
  public static void main(String[] args) {
    int count = 0; // Counts the number of combinations

    //your code here

    // Display total number of all combinations
    System.out.println("The total number of all combinations is " + count);
  }/* w  ww.j ava 2s  . c  o  m*/
}





public class Main {
  public static void main(String[] args) {
    int count = 0; // Counts the number of combinations

    for (int number1 = 1; number1 < 7; number1++) {
      for (int number2 = number1 + 1; number2 <= 7; number2++) {
        System.out.println(number1 + " " + number2);
        count++; // Increment count
      }
    }

    // Display total number of all combinations
    System.out.println("The total number of all combinations is " + count);
  }
}
