Variable might not have been initialized error

Question

When i try to compile this:

public static Rand searchCount (int[] x) 
{
    int a ; 
    int b ; 

    ...   

    for (int l= 0; l

        

Answer 1

You haven't initialised a and b, only declared them. There is a subtle difference.

int a = 0;
int b = 0;

At least this is for C++, I presume Java is the same concept.
