楼上的不是java程序，是javascript.
下面我给出java程序：
public class Add
{public static void main(String args[])
{int i,j;
BufferedReader read=new BufferedReader(new InputSreamReader(System.in));
System.out.println("请输入第一个数：");
String s1=read.readLine();
i=Integer.parseInt(s1);

System.out.println("请输入第二个数：");
String s2=read.readLine();
j=Integer.parseInt(s2);
int sum=i+j;
System.out.println("sum="+sum);

}
}

也可以用一个数组来接收从键盘的输入值,主要的还是要通过System.in()来接收读入的值

wen00000000 · 2004-06-09

public class aaaa {
public static void main(String[] args) {
if(2<args.length) System.exit(0);
String[] a=new String[2];
a[0]=args[0];
a[1]=args[1];
int x=Integer.valueOf(a[0]).intValue();
int y=Integer.valueOf(a[1]).intValue();
System.out.println(x+y);
}
}
Run it when complie to JAR file:
java -jar aaaa.jar 123 456
output: 579
