Question

HELLO, I really need help on a java project. It involves methods and getting data from other classes.

Answer 1

//AddNumbers.java
public class AddNumbers {
  int n1, n2;

  public AddNumbers(int n1, int n2) {
    this.n1 = n1;
    this.n2 = n2;
  }

  public int getN1() {
    return n1;
  }

  public void setN1(int n1) {
    this.n1 = n1;
  }

  public int getN2() {
    return n2;
  }

  public void setN2(int n2) {
    this.n2 = n2;
  }

  public int getSum(){
    return n1+n2;
  }
}

====================================

//TestCode.java
public class TestCode {
  public static void main(String args[]){
    AddNumbers object = new AddNumbers(3,4);
    System.out.println("Sum = "+object.getSum());
  }
}

====================================

Sum = 7
