Whenever we declare a constant in java its value tends to be the same throughout the entire program. In the case of a normal variable, we can change the assigned value. Java doesn’t allow the use of constants directly so we use static and final non-access modifiers. The main motive of using constants is to decrease repeatability in the code with some standard values. It is cached by the Java Virtual Machine and written code results in improvement of the

In this article, we will discuss about nested switch in Java with examples. When a switch statement contains further switch statements inside it, then it is called a nested switch. Inside the nested switch statement, we can give multiple cases and a default case. The inner switch statement must be part of any outer case statement. We cannot use the inner switch statements outside the cases.

To plan or decide something before implementation is always essential. This will help execute every step more efficiently, and you have an idea about the action that to be performed next. In computer language, decision-making is an important part. Predominantly, the execution starts from the top to the bottom. But sometimes, the decision is vital to know which block needs to perform next. Control flow in Java will help you to decide the next action. This article gives detailed information

It is pretty impossible to impose hundreds of words or numbers by just writing or putting into variable one by one. Instead, use a loop to avoid extra time. This article gives an overview of nested while loop in Java and how to use them. Why use loops? Loops are the programming structure of an operation that repeats in a specific sequence until the particular condition or procedure is completed. Loops follow the don’t repeat yourself (DRY) principle for complete
