python复制代码for i in range(5):print(i)输出：复制代码01234 在这个例子中，range(5) 生成了一个从 0 到 4 的整数序列（注意结束值 5 不包含在内），for 循环依次将序列中的每个整数赋值给变量 i，并执行循环体内的代码。示例 2：指定开始值和结束值 python复制代码for i in range(2, 7):print(i)...
那就简单理解成int i=-1先执行i++, 然后只要(i<N)成立, 就循环{循环体}我没把i++写后面的原因...

String s = “I AM an Object!”; boolean isObject = s instanceof Object; 我们声明了一个String对象引用,指向一个String对象,然后用instancof来测试它所指向的对象是否是Object类的一个实例,显然,这是真的,所以返回true,也就是isObject的值为true。
(1)在第一行程序中(for i in range(1,10):),变量i的数据范围为1到9。(2)同理,在第二行的程序中(for j in range(1,i+1):),变量j的数据范围为1到i。(3)如果“%d”表示十进制数,那么%nd则表示n位宽的十进制数,%2d则表示2位宽的十进制数。(4)第三行程序改为print("%d X %d=%2d"%(...
fori inrange(1,6):ifi ==3:breakprint(i) 输出结果为: 12 六、嵌套循环的应用 通过嵌套for循环,我们可以处理更复杂的迭代任务,例如遍历多维列表或执行嵌套循环。示例代码如下: matrix=[[1,2,3],[4,5,6],[7,8,9]]for row in matrix:for element in row:print(element) ...
