JAVA两个数的交换

  public static void main(String[] args) {
        int a,b,c;
        a=10;
        b=15;
        System.out.println("运行前");
        System.out.println(" a="+a+" b="+b);
        c=a;
        a=b;
        b=c;
        System.out.println("运行后");
        System.out.println(" a="+a+" b="+b);

    }
}

运行前
a=10 b=15
运行后
a=15 b=10

Process finished with exit code 0
