java中一个值得注意的问题---类成员初始化与变量初始化的区别

1、code1

class Change
{
	int x;
}
public class JavaTest1
{
	public static void main(String[] agrs)
	{
		Change c=new Change();
		System.out.println("The value of c is "+c.x);
	}
}

2、code2

public class JavaTest1
{
	public static void main(String[] agrs)
	{
		int a;
		System.out.println("The value of c is "+a);
	}
}
