「Java」クラスのstatic変数を利用する方法
書式
class class名 {
static 変数の型 method名;
}
Javaコード
package com.arkgame.study; class CftExample { // static変数の定義 string、int、char、long、double、float static String cftA = "tokyo"; static int cftB = 100; static char cftC = 'U'; static long cftD = 49433204432234523L; static double cftE = 6.5; static float cftF = 3.2F; } public class StaticParamterDemo { public static void main(String[] args) { // string System.out.println("stringの値:" + CftExample.cftA); // int System.out.println("intの値:" + CftExample.cftB); // char System.out.println("charの値:" + CftExample.cftC); // long System.out.println("longの値:" + CftExample.cftD); // double System.out.println("doubleの値:" + CftExample.cftE); // float System.out.println("floatの値:" + CftExample.cftF); } }
実行結果
stringの値:tokyo
intの値:100
charの値:U
longの値:49433204432234523
doubleの値:6.5
floatの値:3.2
