What does *= in Java do?
|*||Multiplication||Multiplies two values|
|/||Division||Divides one value by another|
|%||Modulus||Returns the division remainder|
|++||Increment||Increases the value of a variable by 1|
What does /= mean in C programming?
The /= operator first divides the value of the variable or property (on the left-hand side of the operator) by the value of the expression (on the right-hand side of the operator). The operator then assigns the floating-point result of that operation to the variable or property.
What is a logical operator in Java?
A logical operator (sometimes called a “ Boolean operator ”) in Java programming is an operator that returns a Boolean result that’s based on the Boolean result of one or two other expressions. evaluated before the And operator is applied.
What is difference between i ++ and ++ i in Java?
What is the Difference Between i++ and ++i in Java? ++ i and i ++ both increment the value of i by 1 but in a different way. If ++ precedes the variable, it is called pre- increment operator and it comes after a variable, it is called post- increment operator.
Why do we use a constructor?
The purpose of constructor is to initialize the object of a class while the purpose of a method is to perform a task by executing java code. Constructors cannot be abstract, final, static and synchronised while methods can be. Constructors do not have return types while methods do.
What does!= Mean in coding?
The not-equal-to operator (!= ) returns true if the operands don’t have the same value; otherwise, it returns false.
Why is C called C?
C is a general purpose computer programming language developed in 1972 by Dennis Ritchie at the Bell Telephone Laboratories for use with the Unix operating system. It was named ‘ C ‘ because many of its features were derived from an earlier language called ‘B’.
What does /= mean?
/= may refer to: Augmented assignment, an operator for division. Relational operator, a symbol meaning not equal to.
What are the 3 logical operators?
Is == a logical operator?
Comparison operators — operators that compare values and return true or false. The operators include: >, <, >=, <=, ===, and!== Logical operators — operators that combine multiple boolean expressions or values and provide a single boolean output. The operators include: &&, ||, and!.
Is used in Java?
Operator in Java is a symbol which is used to perform operations. For example: +, -, *, / etc. Java Operator Precedence.

Can we have this () and super () together?
Constructor must always be the first statement. So we can not have two statements as first statement, hence either we can call super() or we can call this () from the constructor, but not both. here if oyu use parameter constructor then there will be error.
What does ++ i and i ++ mean?
In C, ++ and — operators are called increment and decrement operators. They are unary operators needing only one operand. Hence ++ as well as — operator can appear before or after the operand with same effect. That means both i ++ and ++ i will be equivalent. i=5; i++; printf(“%d”,i);
When should I use this in Java?
The this keyword refers to the current object in a method or constructor. The most common use of the this keyword is to eliminate the confusion between class attributes and parameters with the same name (because a class attribute is shadowed by a method or constructor parameter).
