int[] numbers = new int[10];
numbers[0] = 20;
At first I thought I was so far off in syntax (I'm more of a C++ programmer), that It wouldn't work. But I whipped out the good ole' Java book and this would be correct.
Is there any obvious reason why Android Studio isn't recognizing this? The first line declaring the array appears to work properly, but the line where I set 20 as the first block is giving me the red squigglies and Unknown Class 'numbers' error.
This is what happens if the code is in a class body and not in a method body.
The declaration on the first line is valid in both class and method bodies. The second line assignment is only valid in a method.
{} block, code such as assignments need to be in function blocks. The compiler expects to see a declaration and emits an error message when the "declaration" has unknown type.Your second line needs to be inside a method (function).
class Foo
{
int numbers[] = new int[10];
Foo()
{
numbers[0] = 20;
}
}
You should assign values in constructor or in some method...
If you are coding for Android then ArrayList is more preferable and easy to use too,
As simple as
ArrayList numbers=new ArrayList();
numbers.add(20);
