Java 中的实例初始化块
javajava programming java 8
实例初始化块用于初始化对象的属性。它在调用构造函数之前被调用。每次创建对象时都会被调用。请参阅下面的示例 −
示例
public class Tester {
{
System.out.println("Inside instance initializer block");
}
Tester(){
System.out.println("Inside constructor");
}
public static void main(String[] arguments) {
Tester test = new Tester();
Tester test1 = new Tester();
}
}
输出
Inside instance initializer block Inside constructor Inside instance initializer block Inside constructor
