Java end program statement

The following example shows how we can return a String from the function. If the value is false , it will return Statement 2 and then ignore Statement 3 as the execution of this method has been completed.

The output prints Statement 1 as well as Statement3, which was ignored in the previous example. It happened because the statement block of if condition has println instead of a return.

This method doesn't return any value. Exit can be disabled by the SecurityManager class. The System. Return statement is usually used to return a value from a function incase the function returns any value , else it is used to terminate a function if it returns void. Return would cause a program to exit , if it's present inside the main method of a class. If you add more code after return, the compiler will complain about unreachable code. What happens if we put some code after return?

Let's see. Every Java application has a single instance of class Runtime that allows the application to interface with the environment in which the application is running. This class has various methods to interact with the environment in which the Java virtual Machine is Running. Few uses of this class include:. It is the halt method of this Runtime class that we're interested in.

When you call the exit method , the Shutdown sequence is started , Shutdown Hooks or Exit finalizers are called. These Hooks are pieces of code to be executed when the JVM is shutting down. The Halt method forcibly terminates the JVM , hence no hooks are called.

It only works on switch, for, while and do loops. So in your example the break would terminate the for loop. See this section and this section of the Java tutorial. The most important distinction between the two is that Java fields can hold information, while Java methods perform a task. On its own, a Java field only describes the type of information stored. Java fields and methods can also be declared with other modifiers.

Constructor is used to initialize an object whereas method is used to exhibits functionality of an object. Constructors are invoked implicitly whereas methods are invoked explicitly. The only loop that will always get executed is the do while loop.
