環境
Eclipe 2019
Java 8
書式
double 変数A = 値
int 変数B = (int)変数A
使用例
package com.arkgame.Test;
public class IntoDoubleDemo {
public static void main(String[] args) {
int cftA = 123;
// int型からdouble型に変換
double resA = cftA;
System.out.println(resA);
double cftC = 456.78;
// double型からint型に変換
int resB = (int) cftC;
System.out.println(resB);
}
}
package com.arkgame.Test;
public class IntoDoubleDemo {
public static void main(String[] args) {
int cftA = 123;
// int型からdouble型に変換
double resA = cftA;
System.out.println(resA);
double cftC = 456.78;
// double型からint型に変換
int resB = (int) cftC;
System.out.println(resB);
}
}
package com.arkgame.Test;
public class IntoDoubleDemo {
public static void main(String[] args) {
int cftA = 123;
// int型からdouble型に変換
double resA = cftA;
System.out.println(resA);
double cftC = 456.78;
// double型からint型に変換
int resB = (int) cftC;
System.out.println(resB);
}
}
