Java: How can a constructor return a value? [duplicate]

Answer 1

To pass back a value from a constructor - just pass in an array as a parameter. To illustrate the principle:

Test() {
    Boolean[] flag = new Boolean[1];
    flag[0] = false;
    new MyClass(flag);
    System.out.println(flag[0]); // Will output 'true'
}

class MyClass {
    MyClass(Boolean[] flag) {
        // Do some work here, then set flag[0] to show the status
        flag[0] = true;
    }
}
