What does '*' mean in Java?

* (Multiplication) Multiplies values on either side of the operator. A * B will give 200. / (Division) Divides left-hand operand by right-hand operand.

What is the meaning of *=?

What does -= mean in programming?

-= Operator (Visual Basic)

Subtracts the value of an expression from the value of a variable or property and assigns the result to the variable or property.

Is it += or =+ in Java?

It's the Addition assignment operator. Let's understand the += operator in Java and learn to use it for our day to day programming. x += y in Java is the same as x = x + y. It is a compound assignment operator.

What does *= do in Java?

In Java, the *= is called a multiplication compound assignment operator. It's a shortcut for density = density * invertedRatio; Same abbreviations are possible e.g. for: String x = "hello "; x += "world" // results in "hello world" int y = 100; y -= 42; // results in y == 58. and so on.

Why +( I 1 )+ is used in Java?

The increment (++) operator (also known as increment unary operator) in Java is used to increase the value of a variable by 1. Since it is a type of a unary operator, it can be used with a single operand.

What does J += J ++ mean in Java?

Also, j++ means returns the current value of j and then increment it by one. In your case, since you do j = j + j++ you first read j , then you read j again and returns the value of j . Let's do an example with the first iteration: You read j = 0. You read j = 0 again.

What is ++ I and I ++ in Java?

both are incrementing the value of variable i++ is first initalize the value then incriment the value of variable, then ++i it indicates first increment the value then initialize the value. i++ refers to post increment. ++i refers to pre increment. It increments value of i by 1 and returns original value.

What is ++ I versus I ++?

The only difference is the order of operations between the increment of the variable and the value the operator returns. So basically ++i returns the value after it is incremented, while i++ return the value before it is incremented. At the end, in both cases the i will have its value incremented.

What is * operator used for?
