答案如下:
//filename: T3_12.java
import java.util.* ;
public class T3_12
{
public static void main(String[] args)
{
int num1,num2;
Scanner reader = new Scanner(System. in);
System.out.print(“请输入第一个数:”);
num1 = reader.nextInt();
System.out.print(“请输入第二个数:”);
num2 = reader.nextInt();
System.out.println(num1+"/"+num2+"="+((float)num1/num2));
}
}
