Definition:
There are two equality operators used to determine whether equality or inequality exists between two operands:
== is equal to.
!= is not equal to.
Both operators return a boolean value; true if the result of the equality operation is correct, otherwise false.
Examples:
int value = 10;
//does the value variable equal ten?
boolean isEqual = value == 10;
//does the value variable not equal ten?
boolean isNotEqual = value != 20;
//Normally they are used as part of a control flow statement
if (value == 10)
{
System.out.println("Yay, the value is 10");
}
