The Unary Operators in Java
In this example we will see how we can make use of the
unary operator. In java we have been provided the unary operators so we should
know how to make use of those operators. Unary operators are:
++expr, --expr, +expr, -expr, ~, !
Description of program:
In this section we will know how to make use of the unary
operators in java. First all of, we have to define a class "UnaryOperation"
. Inside this class we have defined one class variable. We are making one
overloaded main method which takes one integer type argument. Define one method
operate() of type int where we are going to use the various unary
operators. At last inside the main method call the method operate() so
that the result can be displayed to the user. The output will be displayed
on the screen by using the println() method of the System class.
Here is the code of this program
class UnaryOperation {
public static int i=0;
public static void main(int i){
i=i;
}
public static int operate(){
int i = +1;
System.out.println(i);
i--;
System.out.println(i);
i++;
System.out.println(i);
i = ++i;
System.out.println(i);
boolean success = false;
System.out.println(!success);
System.out.println(success);
return 0;
}
public static void main(String args[])
{
UnaryOperation uo= new UnaryOperation();
int i=uo.operate();
}
}
