Java Fundamentals----branching structures and loops

One. Last talk about if and if---else branch structure, this time if---else if, and switch---case

1. if (Boolean) {

Statement

}

else if (Boolean) {

Statement

}

else{

Statement

}

2. Switch (Boolean) {///Advantage structure is clear, high efficiency, the disadvantage can only judge the case of equal numbers.

Case 1:

Statement

Case 2:

Statement

。。。。。。

Default:

Statement

}

Two. Cycle

Three elements of the loop:

1. Loop variable Initialization

2. Cyclic conditions (based on cyclic variables)

3. Change of the cyclic variable (toward the end of the loop)

1. Whlie (Boolean) {

   Statement

   }

B. do{

Statement


}whlie (Boolean)
