Syntax error when returning an array

[wantakill]

Hi,

I'm totally new to Java. I try to return an array of two strings. Somehow, I can't return the array value. In the suggestion box from java, it suggests that I create a local array value (I already defined this array value in the for loop). Please help me point out the error in my code.

Thx in advance.

P.V.

public String[] AccInformaion(int CustomerAccNumber)
{
String[] name = {"X","Y","Z"};
double[] balance = {1500,10000,10};
int[] AccNumber = {123,456,789};

for(int i = 0; i <= (AccNumber.length -1);i++)
{
if (CustomerAccNumber == AccNumber[i])
{
String customerBalance_S = Double.toString(balance[i]);
String[] value = {name[i],customerBalance_S};

}
else
{
...
}

}

return value;
}

This is a scope issue. When you exit the if and for statements, the variable 'value' no longer exists as it is local to that part of the code only.

That is,

int a = 5;
if (true) {
    int b = 6;
    while (false) {
        int c = 7;
        // Here, a, b, and c are accessible.
    }
    // Here, a and b are accessible.
}
// Here, a is accessible.

What you'll want to do is either declare value as an empty String array at the start of the function, or return the value as soon as it is defined.
