yoda condition

Consider the following 2 conditions in Java

Example

public class Test {
	public static void main(String[] args) {
		String s;
		s = "yoda";
		if (s == null) {

		}
		// yoda condition
		if (null == s) {

		}
	}
}

They both result in the same behavior, but the second one has one advantage: It prevents you from accidentally changing a variable, when you forget one =. In that case the compiler returns an error at that row and you’re not left with some weird behavior of your code and the resulting debugging. The second condition is called a Yoda Condition
