'i don't know how to use the return statement here '
And you can't read the documentation ?

Thank you, Carlo.

## Solution 2

When you write a Java method[^] you can specify a return type - a type of value that the method passes back to the caller when it is finished. The return type can be anything: integer, double, boolean, a class you wrote: any single type name that you can put in front of a variable name when you declare it.

And the system then knows that you will provide a value when the method is called. To provide that value, you use the `return` statement supplying the value to return.
For example, a JAva method to add two numbers could be:
Java
```static int Add(int x, int y){
int result = x + y;
return result;
}```
This takes two parameters called x and y both of which are integers, adds them together, and returns the resulting value.

Your need for a `return` in your code means you probably need a method which accepts an array of integers, and returns an integer:
Java
```static int GetBiggest(int[] arr){
int biggest;
...
return biggest;
}```
All you need to do is fill in the code in the middle.

## Solution 3

Try
Java
```public class Max
{
public static int findMax( int a[])
{
int max = a[0];
for( int x : a)
if ( max < x )
max = x;
return max;
}

public static void main(String args[] )
{
int A[] = {1, 8, 7, 56, 90 };

int max = findMax(A);
System.out.printf("Maximum value is %d\n", max);

}
}```
