## How does & work in Java?

The & operator is a bitwise “And”. The result is the bits that are turned on in both numbers. 1001 & 1100 = 1000 , since only the first bit is turned on in both. The | operator is a bitwise “Or”.

## How does modulus work in Java?

Java has one important arithmetical operator you may not be familiar with, % , also known as the modulus or remainder operator. The % operator returns the remainder of two numbers. For instance 10 % 3 is 1 because 10 divided by 3 leaves a remainder of 1.

## What does &= mean in Java?

boolean operands

## What is ++ i and i ++ in Java?

Both increment the number, but ++i increments the number before the current expression is evaluted, whereas i++ increments the number after the expression is evaluated. int i = 3; int a = i++; // a = 3, i = 4 int b = ++a; // b = 4, a = 4.

## What is the use of || in Java?

The Logical OperatorsOperatorDescription|| (logical or)Called Logical OR Operator. If any of the two operands are non-zero, then the condition becomes true.! (logical not)Called Logical NOT Operator. Use to reverses the logical state of its operand. If a condition is true then Logical NOT operator will make false.

## Can you use += in Java?

As long as x and y are of the same type (for example, both are int s), you may consider the two statements equivalent. However, in Java, x += y is not identical to x = x + y in general. += performs an implicit cast, whereas for + you need to explicitly cast the second operand, otherwise you’d get a compiler error.

## How does modulus work?

The modulus operator – or more precisely, the modulo operation – is a way to determine the remainder of a division operation. Instead of returning the result of the division, the modulo operation returns the whole number remainder. … That remainder is what the modulo operation returns.

## What is print () in Java?

print(): print() method in Java is used to display a text on the console. This text is passed as the parameter to this method in the form of String. This method prints the text on the console and the cursor remains at the end of the text at the console. The next printing takes place from just here.

## What is mod in Java?

Java has one important arithmetical operator you may not be familiar with, % , also known as the modulus or remainder operator. The % operator returns the remainder of two numbers. For instance 10 % 3 is 1 because 10 divided by 3 leaves a remainder of 1.

## What is difference between & and && in Java?

& is a bitwise operator and compares each operand bitwise. Whereas && is a logical AND operator and operates on boolean operands. … If both the operands are true, then the condition becomes true otherwise it is false.

## What does three dots mean in Java?

Variable Arguments

## What is ++ A in Java?

In programming (Java, C, C++, JavaScript etc. ), the increment operator ++ increases the value of a variable by 1. Similarly, the decrement operator — decreases the value of a variable by 1. a = 5 ++a; // a becomes 6 a++; // a becomes 7 –a; // a becomes 6 a–; // a becomes 5. Simple enough till now.

## What does Java mean?

Java is a high-level programming language developed by Sun Microsystems. It was originally designed for developing programs for set-top boxes and handheld devices, but later became a popular choice for creating web applications. The Java syntax is similar to C++, but is strictly an object-oriented programming language.
