最终可以在Java中不受阻碍地使用块吗?
是的,最终使用catch块不是强制性的。您可能必须尝试最后。
示例
public class Test { public static void main(String args[]) { int a[] = new int[2]; try { } finally { a[0] = 6; System.out.println("First element value: " + a[0]); System.out.println("The finally statement is executed"); } } }
输出结果
First element value: 6 Exception in thread "main" The finally statement is executed java.lang.ArrayIndexOutOfBoundsException: 3 at a5Exception_Handling.Test.main(Test.java:7)
