✏️ Astatic initialization blockis a normalblock of codeenclosed in braces { } , and preceded by thestatickeyword. 📜 如上所示:静态初始化块就是一个普通的代码块,它包含在花括号 { } 中,花括号的前方有一个static关键字。 ✏️ A class
下面是一个使用静态代码块进行初始化的示例: publicclassStaticInitializationExample{staticintcount;staticStringmessage;static{count=5;message="Hello, world!";System.out.println("Static initialization block executed.");}publicstaticvoidmain(String[]args){System.out.println("Count: "+count);System.out.pri...
HackerRank之Java Initializer Block Static initialization blocks are executed when the class is loaded, and you can initialize static variables in those blocks. It's time to test your knowledge ofStatic initialization blocks. You can read about ithere. You are given a classSolutionwith amainmethod....
classEmployee47{private static int nextId;private int id;private String name;private double salary;// object initialization block{id=nextId;nextId++;}publicEmployee47(String n,double s){name=n;salary=s;}publicEmployee47(){name="";salary=0;}// ...} 在这个示例中,无论使用哪个构造器构造对象...
initializationblock.method(); System.out.println("---");//多打印几个对象的目的是:好看出Static静态代码块只执行一次!!!Initializationblock initializationblock2 =newInitializationblock();//因为静态块是在类的初始化阶段完成的,因此在创建某个类的第二个对象时,该类的静态块就不会执行了initializationblock...
输出: 初始化块部分: 这一部分就是初始化块 (initialization block),用来初始化数据域。在一个类的声明中,可以包含多个代码块。只要构造类的对象,这些块就会被执行。
package com.gx.initializationblock; public class Initializationblock { int intA; int intB; public Initializationblock() { System.out.println("无参构造器00000000"); } public Initializationblock(int a) { System.out.println("一个参数的构造器"); ...
在Java中，静态初始化块(static initializer block)是在类加载时执行的，而不是在实例化对象时执行的。
Static Initialization Blocks Astatic initialization blockis a normal block of code enclosed in braces,{ }, and preceded by thestatickeyword. Here is an example: static { // whatever code is needed for initialization goes here } A class can have any number of static initialization blocks, and ...
public class CodeBlock { static{ System.out.println("静态代码块"); } }由于静态代...
