Switch Statement

Chapter

Abstract

Utilizing a switch conditional statement instead of an if statement can sometimes present clearer code logic. When we have a variable or an expression containing variables that may have different resulting values followed by different actions, it is a good opportunity to use switch.

switch (<expression>) {
       case <result 1>:
              <action 1>;
              break;
       case <result 2>:
              <action 2>;
              break;
       ……
       case <result n>:
              <action n>;
              break;
       default:
              <other action>;
              break;
}
