java static 调用 java static用法

1、修饰方法、变量

2、修饰代码块

3、静态内部类

4、静态导包

 

package com.shob.oth;

import java.util.Objects;
import static java.lang.System.out;

public class Other {

	static{
		
		System.out.println("12331");
	}
	
	private static String st = "xx";
	
	public static void main(String[] args) {
		int a =0,b=0;
		System.out.println(Objects.equals(a, b));
		out.println("123");
		for (int i = 0; i < 2; i++) {
			a+=i;
			System.out.println(i);
		}
		
		Tes tes = new Tes();
		tes.setIak("1");
		tes.setIdk("2");
		
		String s = "1";
		String s1 = "1";
		System.out.println(Objects.toString(tes));
		
		System.out.println(Objects.deepEquals(s, s1));
		
		
		SClazz sc = new SClazz();
	}
	
	static class SClazz{
		static{
			System.out.println("12");
		}
	}
	
}
