Local Variable Probelm

Question

public class Q275d {
    static int a;
    int b;
    public Q275d() {
        int c;
        c = a;
        a++;
        b += c;
    public static void main(String[] args) {
        new Q275d();
}Since int c is not initialized . It shud give a compiilation error. But it does not. What is the reason behind this. I thought it was a local variable

Since int c is not initialized . It shud give a
compiilation error. But it does not. What is the
reason behind this. I thought it was a local
variableYou're initializing it when you say c = a;Perhaps you thought you had to initialize it on the line where you declare it? As in int c = a;You don't need to do that. You just have to initialize it before you try to read its value. Of course, if you know what value you're going to give it at the point of declaration, it's generally considered good practice to do so.
