Java provides three logical operators such as :

• && Logical-AND
• || Logical-OR
• ! Logical not

The logical operators && and || are used when we want to form compound conditions by combining two or more relations. For example:

X < y && x+y > y

Here this expression contains two expressions combined by && operator.

• • So according to the concept, if both expressions are true, then the output will be true, otherwise it will be false.
• • In case of logical or (||) operator, if any one expression is true, then the result is true, otherwise it is false.

Let's see a program :

class LogicalDemo
{
	public static void main(String args[])
	{
		int x=10,y=15;
		boolean p;
		boolean q;
		p=(x<y)&&((x+y)>x);
		q=(x>=y)||((x+y)<x);
		System.out.println(p);
		System.out.println(q);
	}
}

Output:

true
false
