「Java」switch文を使うサンプル
構文
switch(条件式}{
case 定数1:処理1;
case 定数2:処理2 ;
default:処理
}
Javaコード
package com.arkgame.study;
public class SwitchDemo {
public static final boolean flgA = true;
public static final boolean flgB = false;
public static boolean showRes(String target) {

case "AA10":
return flgA;

default:

}
}
public static void main(String[] args) {

System.out.println("変数Aの関数処理後結果：" + showRes(strA));
System.out.println("変数Bの関数処理後結果：" + showRes(strB));
System.out.println("変数Cの関数処理後結果：" + showRes(strC));
