The iteration statements allow a set of instructions to be performed repeatedly until a certain condition is fulfilled. The iteration statements are also called loops or looping statements. Java provides three kinds of loops: for loop, while loop, and do-while loop. All three loop constructs of Java repeat a set of statements as long as […]

The switch and if-else both are selection statements, and they both let you select an alternative out of the given many alternatives by testing an expression. However, there are some differences in their operations. These are given below: switch if-else the switch can only test for equality if can evaluate a relational or logical expression […]

Java provides a multiple-branch selection statement known as a switch. This selection statement successively tests the value of an expression against a list of integer or character constants. When a match is found, the statements associated with that constant are executed. Syntax: The syntax of the switch statement is as follows: The expression is evaluated, […]

if-else ladder: The if-else-if ladder statement is used to test multiple conditions in Java. It’s used to test a single condition from a set of statements. When there are multiple conditions to execute, the if-else-if ladder makes the code easy to understand and work with. Syntax: If Else If Block data flow diagram: Example: Output: […]

The selection statement allows choosing the set of instructions for execution depending upon an expression’s truth value. Java provides two types of selection statements – if and switch. In addition, the’:?’ (ternary operator) is also used. The selection statements are also called conditional statements or decision statements. The if statement is used to test particular […]

In Java, type casting is a method or process for manually and automatically converting one data type into another. The compiler performs the automatic conversion, while the programmer performs the manual conversion. In this section, we’ll go over typecasting and the various types with examples. Types of Type Casting There are two types of typecasting: […]

Operator precedence determines the order in which the operators in an expression are evaluated. Associativity rules determine the grouping of operands and operators in an expression with more than one operator of the same precedence. Operators Precedence Associativity postfix increment and decrement ++ — left to right prefix increment and decrement, and unary ++ — […]

The operators in Java represent the operations, i.e, operators perform operations on the operands. Let us discuss the various operators in Java. Arithmetic Operators: These operators are for basic arithmetic operations They are additions, subtraction, multiplication, division, and remainder. Each of these operators is binary, i.e, it requires two values (operands) to calculate the final […]

In programming, a constant is an immutable entity. To put it another way, the value cannot be altered. In a program, we often want to give a name to a constant value. For instance, we might have a fixed tax rate of 0.030 for goods and a tax rate of 0.020 for services. These are […]

Variables represent named storage locations, whose values can be manipulated during the program run. For instance, to store the name of a student and marks of a student during a program run, we require storage locations that are too named so that these can be distinguished easily. Declaration of variables: The declaration of a variable […]
