OPERATORS AND EXPRESSIONS IN JAVA by Shameem Singh

Define an operator with example ?

shameemsingh — 2020-07-22 11:08:45 UTC

+, -, >, ? %

Define an operand.

shameemsingh — 2020-07-22 11:10:41 UTC

Variables or constants on which the operators work.
Ex. A, 10, B, sum, x,y , 6.89

Define an expression with example.

shameemsingh — 2020-07-22 11:15:14 UTC

A combination of valid java identifiers, constants, functions and operators that gives a specific result is called an expression.
Example : a= b+c-d
or x= y*y + z*z or y =x/3

What is a binary operator?

shameemsingh — 2020-07-22 11:25:54 UTC

+, -, %, *, /, >, < ,=, ==,!=

An assignment operator assigns or stores a value .For example - C=A+B.where is equal to sign is the assignment operator.

OPERATORS USED TO ASSIGN VALUES OF AN EXPRESSION TO AN OPERAND.

prakharyadav6oct2006 — 2020-08-06 03:41:31 UTC

THEY ARE USED TO ASSIGN VALUES TO A VARIABLE. The left side operand of the assignment operator is a variable and right side operand of the assignment operator is a value.
EXAMPLE OF IT IS - int Y = 15.

It assigns a value on the right hand side of an expression.

utkarshgupta25jan2008 — 2020-08-06 03:41:38 UTC

Example: int a=234,
But a+b=c is wrong.
We can write it as c=a+b
= operator is the assignment operator.

devarchitsingh2mar2007 — 2020-08-06 03:41:38 UTC

Assignment operator assigns a value to the operand on the right-side of the expression. Example: int a=15, double interest=19.6. in this = is the assignment operator.

ASSIGNMENT OPERATOR

eklavyarudra10jan2007 — 2020-08-06 03:41:49 UTC

THIS OPERATOR ASSIGNS A VALUE ON THE RIGHT HAND SIDE OF A EXPRESSION TO THE OPERAND ON THE LEFT HAND SIDE
EG- X=25

Answer:

kalravrastogi1aug2006 — 2020-08-06 03:42:12 UTC

Assignment operator assigns a value in the right hand side of an expression to the operand on the left hand side

the assignment operator, =, is the operator used for assignment.For example a = 10; b = 20; ch = 'y'; “+=”

MANAN SRIVASTAVA-:
Assignment operators assigns a value on the right hand side of the expression and the operand on the left hand side

Manvi Yadav

2020-08-06 03:44:44 UTC

Assignment operated assings a value on the right side of an expression to the operand on the left side example int X=20 etc

This operator assigns or stores a value. Example c=a+b

vaibhavtrivedi23oct2006 — 2020-08-06 03:45:12 UTC

2020-08-06 03:47:19 UTC

Assingement operator assingns a value on the right- hand side of an expression to the operand on the left- hand side.Ex-,int=25,float pi=3.14, double interest =10.5 etc.

Operators that work only on one operand.

shameemsingh — 2020-08-06 07:45:02 UTC

Arithmetic unary operators are
(+) in +2, +8
(-) in -12, -9
++ or the increment operator adds 1 to the operand.
- - or the decrement operator subtracts 1 from the operand
Logical unary operand is (!)
it reverses the result of a boolean expression.
example a=5, b=6
a>b will give false but
!(a>b) will give true.

Tell the output of the following Java statements if a=7,b=4 System.out.println(“sum is”+a+b); System.out.println(“sum is”+(a+b)); System.out.println(“result is”+(a%b)); System.out.println(“result is”+(b%a)); System.out.println(“result is”+(a/b)); System.out.println(“result is”+(a!=b)); System.out.println(“a is equal to be is”+(a==b));
