Yoda conditions in java

 In programming jargon, Yoda conditions (also called Yoda notation) is a programming style where the two parts of an expression are reversed from the typical order in a conditional statement. A Yoda condition places the constant portion of the expression on the left side of the conditional statement.

Usually a conditional statement would be written as:

if ($value == 42) { /* ... */ }

// Reads like: "If the value equals 42..."

Yoda conditions describe the same expression, but reversed:

if (42 == $value) { /* ... */ }

// Reads like: "If 42 equals the value..."
