「Java」static final修飾子で定数を定義するサンプル

書式
class class名 {
static final 変数の型 変数名 = 値;
}
Javaコード

package com.arkgame.study;

class KdfExample {
      // static final変数の定義 string、int、char、long、double、float
      static final String cftA = "tokyo";
      static final int cftB = 200;
      static final char cftC = 'K';
      static final long cftD = 49433204432234523L;
      static final double cftE = 6.7;
      static final float cftF = 3.4F;
}

public class StaticParamterDemo {

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

            System.out.println("実行結果");
            // string
            System.out.println("stringの値:" + KdfExample.cftA);
            // int
            System.out.println("intの値:" + KdfExample.cftB);
            // char
            System.out.println("charの値:" + KdfExample.cftC);
            // long
            System.out.println("longの値:" + KdfExample.cftD);
            // double
            System.out.println("doubleの値:" + KdfExample.cftE);
            // float
            System.out.println("floatの値:" + KdfExample.cftF);
      }
}

実行結果
stringの値:tokyo
intの値:200
charの値:K
longの値:49433204432234523
doubleの値:6.7
floatの値:3.4
