title: Continue Control Statement

# Continue Control Statement
|
||
|
|
|
||
|
|
The `continue` statement makes a loop skip all the following lines after the continue and jump ahead to the beginning of the next iteration. In a `for` loop, control jumps to the update statement, and in a `while` or `do while` loop, control jumps to the boolean expression/condition.
|
||
|
|
|
||
|
|
```java
|
||
|
|
for (int j = 0; j < 10; j++)
|
||
|
|
{
|
||
|
|
if (j == 5)
|
||
|
|
{
|
||
|
|
continue;
|
||
|
|
}
|
||
|
|
System.out.print (j + " ");
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
The value of `j` will be printed for each iteration, except when it is equal to `5`. The print statement will get skipped because of the `continue` and the output will be:
|
||
|
|
|
||
|
|
0 1 2 3 4 6 7 8 9
|
||
|

Say you want to count the number of `i`s in a the word `mississippi`. Here you could use a loop with the `continue` statement, as follows:
|
||
|
|
|
||
|
|
```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);
|
||
|
|
```

Additionally, you can use labels to choose a specific loop out of a nested set to skip to the next iteration.
