This post is in continuation to exploring little-known features of Java. In the previous post, I covered some very surprisingusage of class sun.misc.Unsafe. In this post, I am discussing a little-known feature ofinitializer blocks. 1. Initializer Blocks An initialization block...
Javainstance initializersare the code blocks containing the instructions to run everytime a new class instance is created. We can use the initializer blocks to write initialization login common to all constructors, which otherwise must be written in each constructor separately. 1. Syntax An instance...
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....
1. "Exception in thread"main" java.lang.ExceptionInInitializerError"意味着异常出现在主线程,并且是LinkageError的一个子类java.lang.ExceptionInInitializerError,这是JVM类加载失败时才抛出的,原因是静态初始化代码中出现了诸如IndexOutOfBoundsException或者NullPointerException这样的RuntimeException。 2. 记住JVM会将...
java.lang.ExceptionInInitializerError 异常的原因 java.lang.ExceptionInInitializerError 异常是 Java 中的一个特殊错误,它表明在初始化一个类的静态变量、静态代码块或枚举常量时,发生了未捕获的异常。这个异常并不是直接抛出的,而是由其他异常(如运行时异常、错误等)在静态初始化过程中触发的。
Similar to static initializer blocks, the root cause of the exception is also preserved: assertThatThrownBy(StaticVar::new) .isInstanceOf(ExceptionInInitializerError.class) .hasCauseInstanceOf(RuntimeException.class); 5. Checked Exceptions As part of the Java language specification (JLS-11.2.3),...
