The finally block executes after the try block, printing its message. Example 3: Resource Cleanup import java.io.*; public class FinallyResourceExample { public static void main(String[] args) { FileInputStream fis = null; try { fis = new FileInputStream("example.txt"); // Perform file...
In the following example, the ArithmeticException occurred in try block but there is no catch block that can handle ArithmeticException so after the execution of finally block, a system generated error message is displayed. publicclassJavaExample{publicstaticvoidmain(Stringargs[]){//now the second ...
publicclassExceptionFinallyInteractionExample{ publicstaticvoidtest(){ try{ thrownewRuntimeException("Exception in try block"); }finally{ System.out.println("Finally block in test method"); } } publicstaticvoidmain(String[] args){ try{ test(); }catch(RuntimeException e) { System.out.println(...
return 1; } finally { return 2; } When the Try block executes its return, the finally block is entered with the reason of returning the value 1. However, inside the finally block the value 2 is returned, so the initial intention is forgotten. In fact, if any of the other code in t...
Another example of finally block and return statement You can see that even though we have return statement in the method, the finally block still runs. classJavaFinally{publicstaticvoidmain(Stringargs[]){System.out.println(JavaFinally.myMethod());}publicstaticintmyMethod(){try{return112;}finall...
We actually don't need a catch block with the finally: we can still let exceptions be passed up to the caller. In this case, we end up with a try/finally block. For example, our method to read a number from a file can look like something this: ...
In Java, a finally block is guaranteed to be executed, unless the virtual machine exits abruptly due to an uncaught exception or a call to System.exit. A finally block is typically used to perform clean-up tasks, such as closing resources that have been opened in a try block. It is ...
System.out.println("finally block"); } } } 清单1 的执行结果如下: 1 2 3 4 the previous statement of try block Exception in thread "main" java.lang.ArithmeticException: / by zero at com.bj.charlie.Test.test(Test.java:15) at com.bj.charlie.Test.main(Test.java:6) 另外,如果...
How Finally works in Java? Here we will throw an error or write an errorounous code that would result in an error and finally block execution. Code: class ExampleFinally { public static void main(String args[]) { try{ int result = 1/0; ...
publicclassFinallyExample{publicstaticvoidmain(String[]args){System.out.println(testFinally());}publicstaticinttestFinally(){try{System.out.println("In try block");return1;// 返回值将在finally块之前被执行}catch(Exceptione){System.out.println("In catch block");return2;}finally{System.out.printl...
