Stop executing further code in Java

Question

I have looked in the Javadoc but couldn\'t find information related to this.

I want the application to stop executing a method if code in that method tells it to do

Answer 1

Just do:

public void onClick() {
    if(condition == true) {
        return;
    }
    string.setText("This string should not change if condition = true");
}

It's redundant to write if(condition == true), just write if(condition) (This way, for example, you'll not write = by mistake).
