java循环语句问题

1)

int[] array=new int[1000];

for(int i=0;i<1000;i++){
array[i]=i;
}

2)

while(判断条件){

...

}

3)

do {

...

}while(判断条件);

public class TestForEach { static String[] str = {"数组的第一个元素","数组的第二个元素","数组的第三个元素","数组的第四个元素"};

public static void main(String[] args) { for(String mystr:str) { System.out.println(mystr); } } }

long limit=20; long factoritl =1; for(int i=1; i<=limit; i++){ factoritl = 1; for(int factor=2; factor<=i; factor++){ factoritl *= factor; System.out.println(i+ "i=is" +factoritl); } }

while(true){

System.out.println("s");

}

do{

System.out.println("s");

}while(true)

for循环 . 例如: for(int i = 0; i<10; i++){System.out.println(i);}

while循环 . 例如: while(true){System.out.println("while死循环");}

do-while循环 . 例如: do{System.out.println("while死循环");}while(true);

增强for循环:

例如: String[] a={"a","b","c","d","e"};

for(String i:a){ System.out.println(i);}

for(object o :ob)

{}

while(){}

do{}while()
