To Demonstrate that Objects may be passed to methods

Here is a Java Program to Demonstrate that Objects may be passed to methods.

class Test {
  int a, b;

  Test(int i, int j) {
    a = i;
    b = j;
  }

  // return true if o is equal to the invoking object
  boolean equals(Test o) {
    if(o.a == a && o.b == b) return true;
    else return false;
  }
}

Here is a Java Program to Execute Above Java Class

class PassOb {
  public static void main(String args[]) {
    Test ob1 = new Test(100, 22);
    Test ob2 = new Test(100, 22);
    Test ob3 = new Test(-1, -1);
    
    System.out.println("ob1 == ob2: " + ob1.equals(ob2));

    System.out.println("ob1 == ob3: " + ob1.equals(ob3));
  }
}

Output of Above Java Program
ob1 == ob2: true
ob1 == ob3: false
