Java- 簡單的運算

//載入Scanner
import java.util.Scanner;

public class i20
{

/**
* @param args
*/

public static void main(String[] args)
{
float i, j;
float k;
Scanner scanner = new Scanner(System.in);
System.out.print("請輸入 i 的整數值：");
i = scanner.nextInt();
System.out.print("請輸入 j 的整數值：");
j = scanner.nextInt();
scanner.close();
System.out.println("變數i="+i);
System.out.println("變數j="+j);
k=i+j;
System.out.println("變數i+j="+k);
k=i-j;
System.out.println("變數i-j="+k);
k=i*j;
System.out.println("變數i*j="+k);
k=i/j;
System.out.println("變數i/j="+k);
}
