Is there any way to make Java pass ints by reference and not value?

Not just ints, but doubles, floats, short, byte, long, etc.

^ All of these pass by value, not reference.

try to pass in an Integer instead of an int

It's not really do-able in Java.

EDIT: You could pass an int[].

Java is a pass by value and Integer is immutable. So no, you cannot pass an ints reference in the arguments of a method.

Makes sense. Thank you

With arrays you can.... Interesting

Just... wrap it in an object.

 

public class MutableInteger {  
  
  private int value; 
  
  public int getValue() {
    return value;
  }  
  
  public void setValue(int value) { 
    this.value = value;
  } 
  
}

Getters and setters to the rescue.

I'm writing this down. Thank you!

^ my bad, haven't tested it, figured it was worth a shot. if you need it, then i'd just make a class with an int field
