Modify to use a for loop.

Question

What will be an ideal response?

Answer 1

```
public void increaseVolumeFor ( )
{
SoundSample [ ] sampleArray = this . getSamples ( ) ;
SoundSample sample = null ;
int value = 0 ;
int index = 0 ;
// loop through all the samples in the array
for ( int i = 0 ; i < sampleArray.length ; i++)
{
sample = sampleArray [ i ] ;
value = sample . getValue ( ) ;
sample . setValue ( value *2 ) ;
}
]
```
If you are using Java 1.5 or above modify it to use a for-each loop.
```
public void increaseVolumeForEach ( )
{
SoundSample [ ] sampleArray = this . getSamples ( ) ;
int value = 0 ;
// loop through a ll the samples in the array
for ( SoundSample sample : sampleArray )
{
value = sample . getValue ( ) ;
sample . setValue ( value * 2 ) ;
}
}
```
