What is a Local Variable?
Answer:
Variables defined inside methods, constructors or blocks are called local variables. The variable will be declared and initialized within the method and it will be destroyed when the method has completed.
In Java, a local variable is a variable that is defined within a method, constructor, or a block of code. It is only accessible within the block of code in which it is declared and cannot be accessed from outside that block. Local variables are created on the stack and their memory is automatically freed when the method, constructor, or block of code execution is completed.
Local variables have a scope that is limited to the method, constructor, or block of code in which they are declared. This means that they are only accessible within the block in which they are declared and cannot be accessed from outside that block. The lifetime of a local variable starts when the method, constructor, or block of code is entered and ends when it is exited.
Here is an example of a local variable in Java:
public void doSomething() { int i = 10; // Use the local variable i here. }
In the example above, the local variable i
is declared within the doSomething
method and is only accessible within that method.
