for循环和while循环的相同点与不同点。
相同点：
同为循环结构，用for语句可以操作的用while大部分也可以操作。
不同点：
for循环格式：
for（条件语句1；条件语句2；条件语句3）{
//执行操作语句
}
while循环格式：
while（条件语句）{
//若条件为真，执行操作语句
}
除格式不同外，两者循环结构也有所不同。
比如：计算1~10的累计相加。
//for循环 int sum = 0; for(int i =1;i<=10;i++){ sum = sum + i; } //while循环 int
sum= 0; int i = 1; while(i<=10){ sum = sum + i; i++; }
如果只有这样的一个代码块那么两者没有什么区别，但如果变成这样： ```java//for循环 int sum = 0; for(int i =1;i<=10;i
++){ sum = sum + i; } System.out.pirntln(sum +i ); //while循环 int sum = 0; int i
= 1; while(i<=10){ sum = sum + i; i++; } System.out.pirntln(sum +i );
输出的结果就会出现差异。前者报错找不到符号，后者输出sum+i的值。
如果不考虑内存并且之后不再使用int i 那么while和for可以随意使用。
否则，for和while就必须选择性使用，具体看需求而定。
还有一个就是无限循环。
//for无限循环 for(; ;){ //语句 //判断条件 //break; } //while无限循环 while(true){ //语句 //判断条件
//break; }
