Methods in Java is a block of statements that must be in a class and can be executed by calling it from other places.

Arrays are a collection of elements having same type. To declare an array, we define the variable type with square brackets.

While-loop executes a block of code as long as a specified condition is true.

In this tutorial, you will learn how to create a for loop. A loop is used to repeat a specific block of code until the condition is met.

Switch Statement is used when we want to check equality of a variable against number of values.

If statement is the most basic way of test a condition. With the if statement you test if a condition is true or false.
