Let’s see below all available relational operators in java. They are mostly used in Java control statements such as if statements, while statements etc.

The result produced by a relational operator is always a Boolean value true or false.

All relational operators are binary operators.

String str3 = str1 + str2 // Assigns "I am null" to str3 5. If a reference variable contains the ‘ null‘ reference, the concatenation operator uses a string “null”. String str2 = num + str1 // Assigns "26Alphabets" to str2 4.3. The string concatenation operator is also used to concatenate a primitive and a reference data type value to a string. String str3 = str1 + str2 // Assigns "Hello World" to str3 4.2. It can also be used to concatenate two strings. So far, you have seen its use as an arithmetic addition operator to add two numbers. An operator is said to be overloaded if it is used to perform more than one function. Modulus – Divides left hand operand by right hand operand and returns remainder Multiplication – Multiplies values on either side of the operatorĭivision – Divides left hand operand by right hand operand Subtraction – Subtracts right hand operand from left hand operand Binary Arithmetic Operators OperatorĪddition – Adds values on either side of the operator Logical complement operator inverts the value of a booleanģ.2. Increment operator increments a value by 1ĭecrement operator decrements a value by 1 Unary minus operator negates an expression value

Unary plus operator indicates positive value (numbers are positive without this, however) These operators cannot have operands of boolean primitive type and reference type.It means, both operands to arithmetic operators must be one of types byte, short, char, int, long, float, and double. It can only be used with numeric type operands.

Operators like ( + (plus), – (minus), * (multiply), / (divide)) are called arithmetic operators in Java.

In case of reference variables, you may be able to compile the source code and get a runtime ClassCastException error if the object represented by the right-hand operand is not assignment compatible to the reference variable as the left-hand operand. Java ensures that the value of the right-hand operand of the assignment operator is assignment compatible to the data type of the left-hand operand. counter is the left-hand operand, which is a variable of type int. The left-hand operand must be a variable.The value of the right-hand operand is assigned to the left-hand operand.An assignment operator (=) is used to assign a value to a variable.Let us learn about few most used operators with examples. Type of operation they perform – An operator is called an arithmetic operator, a relational operator, a logical operator, or a bitwise operator, depending on the kind of operation it performs on its operands.If an operator takes one operand, it is called a unary operator if it takes two operands, it is called a binary operator if it takes three operands, it is called a ternary operator. An operator is called a unary, binary, or ternary operator based on the number of operands. Number of operands – There are three types of operators based on the number of operands.

Operators in Java can be categorized based on two criteria: The type of the operator and its operands determine the kind of operation performed on the operands and the type of result produced. Java OperatorsĪn operator is a symbol that performs a specific operation on one, two, or three operands, producing a result. We will also try to understand when to use which operator and what to expect in the result. Learn about available Java operators, and precedence order and understand their usages with examples.
