Use of for loops to iterate Array in Java . dEexams.com

Use of for loops to iterate Array in Java You can iterate a array in Java using for loop.

There are two ways to do that.

Using conventional approach of the "for" loop:

Consider a String array array initialized as follows:
```
String[] array= {"One", "Two", "Three", "Four", "Five"};
```
Now iterate using counter and use of it as the index for the array.
```
for(int i = 0; i< array.length; i++){

System.out.println(array[i]);

}
```
Using foreach loop:

Java provides a way to use the "for" loop that will iterate through each element of the array.Below is the example of it.
```
for (String strTemp : array){

System.out.println(strTemp);

}
```
You can see the difference between the loops. The code has reduced significantly. Also, there is no use of the index or rather the counter in the loop.

Note -Do ensure that, the data type declared in the foreach loop must match the data type of the array/list that you are iterating.

foreach optimizes your loops, saves some typing and of course your time.
