Multidimensional Arrays Data in a table or a matrix can be represented using a two-dimensional array. The preceding chapter introduced how to use one-dimensional arrays to store linear collections of…
Introduction To Array In Java An array is used to store a collection of data, but often we find it more useful to think of an array as a collection…
The if-then Statement The if-then statement is the most basic of all the control flow statements. It tells your program to execute a certain section of code only if a…
Introduction The key benefit of generics is to enable errors to be detected at compile time rather than at runtime. A generic class or method permits you to specify allowable…
Decision Making in Java Decision Making in programming is similar to decision making in real life. In programming also we face some situations where we want a certain block of…
How to Throw Exceptions Before you can catch an exception, some code somewhere must throw one. Any code can throw an exception: your code, code from a package written by…

The finally Block The finally block always executes when the try block exits. This ensures that the finally block is executed even if an unexpected exception occurs. But finally is…
The catch Blocks You associate exception handlers with a try block by providing one or more catch blocks directly after the try block. No code can be between the end…
