JAVA变量初始化及变量作用范围

我将两个示例合并成了一个，来显示JAVA变量作过的范围，

我想在这真正运用的时候，可能才能获得更深入的了解吧。

public class TestVar {
	private int i = 100;
	private static String name = "Learn Java fastly!";
	{
		int block = 10;
	}
	public int firstMethod() {
		int j = 1;
		System.out.println("in firstMethod, we can access  static name :" + name);
		System.out.println("in firstMethod, i = " + i + ", j = " + j);
		return 1;
	}
	public int secondMethod(float f) {
		int j = 2;
		System.out.println("in secondMethod, we can also access  static name :" + name);
		System.out.println("in secondMethod, i = " + i + ", j = " + j + ", f = " + f);
		return 2;
	}
	public static void main(String[] args) {
		TestVar t = new TestVar();
		//System.out.println("in mainMethod, we can access  var block :" + t.block);
		t.firstMethod();
		t.secondMethod(3);
	}
}

 运行结果：
