Java supports shortcut/compound assignment operator. Simple Assignment Operator: The Simple Assignment Operator is used with the = sign where the left side consists of the operand and the right side consists of a value. It adds right operand to the left operand and assigns the result to the left operand. We wont be using any kind of loop in this case, but we are going to see the numerator and the denominator. In the program, we input 100 as a number, and we divide it by 10 using the Compound Division Assignment operator. For example, the preceding statement can be written as: The += is called the addition assignment operator. The |= is a compound assignment operator ( JLS 15.26.2) for the boolean logical operator | ( JLS 15.22.2 ); not to be confused with the conditional-or || ( JLS 15.24 ). Assigning Literal that is too large for a variable, When we try to assign a variable value which is too large (or out of range ) for a primitive variable then the compiler will throw exception possible loss of precision if we try to provide explicit cast then the compiler will accept it but narrowed down the value using twos complement method. The left side operand of the assignment operator is a variable, and the right side operand of the assignment operator is a value. Subtract AND assignment operator. This article will also cover assignment operators. Its syntax is as follows: variable_name=expression ^= Compound bitwise ^ assignment operator. We need to provide casting when we are trying to assign higher precision primitive to lower precision primitive for example If we try to assign int variable (which is in the range of byte variable) to byte variable then the compiler will throw an exception called "possible loss of precision". This website or its third-party tools use cookies, which are necessary to its functioning and required to achieve the purposes illustrated in the cookie policy.

The operator op = is known as a shorthand assignment operator in Java because; v op = expression is shorthand notation for v = v operator expression. The below statement creates space for the Employee reference variable (the bit holder for a reference value) but doesn't create an actual Employee object. We are able to see that the two numbers which have been initialized earlier have been printed. In java we can divide assignment operator in two types : Assignment operator or simple assignment operator Compound assignment operators The Simple Assignment Operator is used with the = sign where the left side consists of the operand, and the right side consists of a value. For example, this does not mean that "a" is equal to "b", instead, it means assigning the value of 'b' to 'a'. Java allows you to combine assignment and addition operators using a shorthand operator. Multiply AND assignment operator. Java too provides many types of operators which can be used according to the need to perform various calculations and functions, be it logical, arithmetic, relational, etc. The remaining operators are %, ^, &, >>, << and >>>The following is the code and output. We see that when we enter the value as 10, that is, we get the sum of the first 10 natural numbers like 45. These operators are used to assign values to a variable. It operates by dividing the current value of the variable on the left by the value on the right and then assigning the remainder to the operand on the left. View complete answer on docs.microsoft.com. Otherwise, the compiler will raise an error. It takes modulus using two operands and assigns the result to the left operand. The following program is a simple example that demonstrates the assignment operators. As the name itself suggests, the assignment operator is used to assign value inside a variable. Assigning a value to can be straight forward or casting. The general format of the assignment operator is. /= Compound division assignment operator. We will input the value of the numerator and divide it by 10 and produce the output to the user. Lets look at each of the assignment operators and how they operate: This is the most straightforward assignment operator, which is used to assign the value on the right to the variable on the left. The compound operator is used where +,-,*, and / is used along with the = operator. The bitwise AND assignment operator ( &=) uses the binary representation of both operands, does a bitwise AND operation on them and assigns the result to the variable. In other words, this program shows the factorial of a number in simple terms. It multiplies right operand with the left operand and assigns the result to the left operand. It operates by dividing the current value of the variable on the left by the value on the right and then assigning the quotient to the operand on the left. Compound-assignment operators provide a shorter syntax for assigning the result of an arithmetic or bitwise operator. The basic advantage of compound assignment operators is that it saves a lot of code within the Java language program. In this section, we will discuss the compound assignment operators in Java. The Assignment Operator is generally of two types. Assigns values from right side operands to left side operand. It includes an assignment operator and arithmetic operator or bitwise operator. Compound assignment operators are used when there are more logical operations are required in the code, like ^, &, %, <>, >>, <<, etc. Compound-assignment operators perform the operation specified by the additional operator, then assign the result to the left operand. The addition assignment operator, +=, is a shorthand way to add a value to a variable. In this case, we are going to see the division of a number using the division operator. In the next program, we are going to see the deletion of numbers from a bigger number 100. The following are all possible assignment operator in java: C = A + B will assign value of A + B into C. +=. Java Assignment Operators are classified into two categories, such as simple and compound assignment operators. For example, this does not mean that "a" is equal to "b", instead, it means assigning the value of 'b' to 'a'.
