How do you power an int in Java?

Use Math.

We can easily calculate the power of an integer with the function Math. pow() provided by the Java library. The number raised to the power of some other number can be calculated using this function. This method takes two parameters; the first number is the base while the second is the exponent.

What is XOR in Java?

JavaObject Oriented ProgrammingProgramming. Bitwise XOR (exclusive or) “^” is an operator in Java that provides the answer ‘1’ if both of the bits in its operands are different, if both of the bits are same then the XOR operator gives the result ‘0’. XOR is a binary operator that is evaluated from left to right.
