Thread: Reading a file, then putting it in an array

For some reason, and I have no idea why. This code doesn't work. I am obviously a newbie to java, and programing in general. But this seems like it would just work. It does so in C++.

public void Read()  //Just Reads the File, does not pass anything back
    {
    String test[];
    int x;
    try {
        BufferedReader readout = new BufferedReader(new FileReader("ClientNames.txt"));
    String names;
    while ((names = readout.readLine()) != null) 
    {
        x++;
        test[x] = names;
        System.out.print(" " + names + ", ");
    }
    readout.close();
    } catch (IOException e) {System.out.println("Could Not Read out file"); }
 
 
    }//End of Read

And i get this error.

x variable might not have been initialized. 
test variable might not have been initialized.

Off to work now, so I wont be able to respond right away. Thanks in advance =)

int x;
try {
BufferedReader readout = new BufferedReader(new FileReader("ClientNames.txt"));
String names;
while ((names = readout.readLine()) != null)
{
x++;

Where is x given a value? The compiler wants to see an assignment statement before you try to use it.

Creating and using arrays is a two step process. First you define the array. Then you define the elements in the array.
String[] anArray; // define an array
anArray = new String[4]; // give the array 4 elements
or
String anArray = new String[5];

public void Read()  //Just Reads the File, does not pass anything back
    {
    String test = new String[100];
    int x =0;
    try {
        BufferedReader readout = new BufferedReader(new FileReader("ClientNames.txt"));
    String names = new String();
    while ((names = readout.readLine()) != null) 
    {
        x++;
        test[x] = names;
        System.out.print(" " + names + ", ");
    }
    readout.close();
    } catch (IOException e) {System.out.println("Could Not Read out file"); }
 
 
    }//End of Read

I did that, and it still gets 2 errors, which are related.

Says

Found java.lang.String;

Required java.lang.String[];

What does this mean? I have the entire java.lang.*; imported

Try

String[] test = new String[100];

When you get errors, please copy and paste full text of the error message here.

That did it. I thought i tried that, but i guess not =)

Thanks for the help guys!
