<>for循环与while循环
一、for循环
1、for为关键字，表示循环控制
2、for有四要素：循环变量初始化、循环条件、循环操作、循环变量迭代
3、循环操作，这里可以有多条语句，也就是我们要循环执行的代码
4、如果 循环操作（语句）只有一条语句，可以省略{}，建议不要省略。
5、基本语法格式
for(循环变量初始化①；循环条件②；循环变量迭代④){
循环体（语句）；③
}
二、while循环
1、与for循环一样，while循环也有四要素，只是位置不一样
2、语法格式
循环变量初始化；①
while(循环条件②){
③
循环体；
循环变量迭代；
}
三、do while循环
基本语法：
说明：
1.do while是关键字
1.也有循环四要素,只是位置不一样
2先执行，再判断,也就是说,一定会至少执行一次
3.最后 有一个分号 ;
4.while和do…while区别举例:要账
while 循环是先问你是否还钱，不还就打；
而do while先打一顿再问
四、比较（执行流程的不同）
1、for循环是先执行①，然后再执行②；
若②满足，则执行③，最后执行④；再执行②，以此循环。
若②不满足，则跳出循环。
2、while循环先执行①，再执行②，如果②满足，则执行③中循环体的内容，否则跳出循环、
上述循环条件里应写只与循环变量迭代有关的表达式，不能写入目标表达式，否则会直接跳出循环。
例：打印1 - 100 之间所有能被3整除的数
public class for02{ public static void main(String[] args) { int i = 1 ;
while( i <= 100){ if( i % 3 == 0) System.out.println("能被三整除的数有："+i); i++; } //
int i = 1 ; // while( i <= 100 && i % 3 == 0){//不能这样写 //
System.out.println("能被三整除的数有："+i); // i++; // } } }
其中明显的区别是
while( i <= 100){
if( i % 3 == 0)
…
不能直接写成
while( i <= 100 && i % 3 == 0)
因为一旦判断条件为假时便直接跳出循环了
