![]() ![]() In this example, we will see how the null pointer is handled by a catch block. ("Array IndexOutOfBounds Exception occurs") (arr) //we want to access 12th element of array which does not exist as size is of 6 In this example, we have illustrated about out-of-bound exception handing for an array by try and catch block. ("ArrayIndexOutOfBounds Exception occurs") This is a simple example of a multi-catch block, where we have written a statement that will generate exceptions inside try block, which will be handled by a corresponding catch block out of three catch blocks. You should try this code by yourself and tally the outputs with the given one. In this section, we will discuss many code examples. MultipleCatchBlockInConstructor mc=new MultipleCatchBlockInConstructor() Public class MultipleCatchBlockInConstructorĬatch(ArrayIndexOutOfBoundsException excp) In the below example, we will write code inside try constructor: try block will generate arithmetic exception which is handled in a catch block. We also can write try-catch blocks inside a constructor and it will work as expected. Program flow will automatically come to the catch block and then, the corresponding exception inside the arguments of catch block is found for the try block and will be handled accordingly. Here you can handle multiple exceptions under a single catch block (separated by pipe sign) for a corresponding try block. Use Multiple Catch Statements in Arguments of A Catch Block: This feature came from Java 7.Program flow will automatically come to the catch block one by one and then, the corresponding catch block is found as per the exception and will be handled accordingly. Use Multiple Catch for a Try Block: Here you can handle multiple exceptions under multiple catch block for a corresponding try block.Now how to deal with multiple exceptions, if any? It contains the code snippet which handles the exception that might occur for the code which is written inside its corresponding try block. At least one catch block is necessary for a try block. ![]() So, whenever you suspect that your code might result in an exception, put that code snippet inside a try block. ![]() It contains the code snippet which may result in exceptions. Syntax 3: try-catch block with multiple catch statements as argument of the catch blockĪt first, we need to check on the try block before moving to catch block. Syntax 2: try-catch block with multiple catch block code snippet which might responsible for exceptions Web development, programming languages, Software testing & others Start Your Free Software Development Course ![]()
