「Java」ラッパーオブジェクトから基本型への変換する
書式
数値.intValue()
使用例
package com.arkgame.strudy.java;
public class InterIntDemo {
private static final Integer count = 678;
public static void main(String[] args) {
change();
}
public static void change() {
int resa = count;
System.out.println("変換結果1: " + resa);
int resb = count.intValue();
System.out.println("変換結果2: " + resb);
}
}
package com.arkgame.strudy.java;
public class InterIntDemo {
private static final Integer count = 678;
public static void main(String[] args) {
change();
}
public static void change() {
int resa = count;
System.out.println("変換結果1: " + resa);
int resb = count.intValue();
System.out.println("変換結果2: " + resb);
}
}
package com.arkgame.strudy.java;
public class InterIntDemo {
private static final Integer count = 678;
public static void main(String[] args) {
change();
}
public static void change() {
int resa = count;
System.out.println("変換結果1: " + resa);
int resb = count.intValue();
System.out.println("変換結果2: " + resb);
}
}
実行結果
変換結果1: 678
変換結果2: 678
