# 继续控制声明
`continue`语句使循环在继续之后跳过所有以下行,并跳转到下一次迭代的开始。在`for`循环中控制跳转到update语句在`while`或`do while`循环中,控制跳转到布尔表达式/条件。
```java
for (int j = 0; j < 10; j++)
{
if (j == 5)
{
continue;
}
System.out.print (j + " ");
}
```
除非等于`5` ,否则将为每次迭代打印`j`的值。由于`continue` 将跳过print语句输出将是
```
0 1 2 3 4 6 7 8 9
```
假设你想要在`mississippi`这个词中计算`i`的数量。在这里,您可以使用带有`continue`语句的循环,如下所示:
```java
String searchWord = "mississippi";
// max stores the length of the string
int max = searchWord.length();
int numPs = 0;
for (int i = 0; i < max; i++)
{
// We only want to count i's - skip other letters
if (searchWord.charAt(i) != 'i')
{
continue;
}
// Increase count_i for each i encountered
numPs++;
}
System.out.println("numPs = " + numPs);
```

此外,您可以使用标签从嵌套集中选择特定循环以跳到下一次迭代。
