//a program to display the numbers after swapping
import java.util.

Scanner in = new Scanner(System.in);
int a,b,c=0;
System.out.println("Enter your number");

}
}
Explain the logic of this Java program.

Answer:
‘Logical AND’ Operator(&&): This operator returns true when both the conditions under consideration are satisfied or are true. If even one of the two yields false, the operator results false. For example, cond1 && cond2 returns true when both cond1 and cond2 are true (i.e. non-zero).
Syntax:
condition1 && condition2
Example:
a = 10, b = 20, c = 20
condition1: a < b
condition2: b == c
if(condition1 && condition2)
d = a+b+c
// Since both the conditions are true
d = 50.

// Java code to illustrate
// logical AND operator
import java.io.*;
class Logical {
public static void main(String[] args)
{
// initializing variables
int a = 10, b = 20, c = 20, d = 0;
// Displaying a, b, c
System.out.println("Var1 = " + a);
System.out.println("Var2 = " + b);
System.out.println("Var3 = " + c);
// using logical AND to verify
// two constraints
if ((a < b) && (b == c)) {
d = a + b + c;
System.out.println("The sum is: " + d);
}
else
System.out.println("False conditions");
}
}
Output:
Var1 = 10
Var2 = 20
Var3 = 20
The sum is: 50
'Logical OR' Operator(||): This operator returns true when one of the two conditions under consideration are satisfied or are true. If even one of the two yields true, the operator results true. To make the result false, both the constraints need to return false.
Syntax:
condition1 || condition2
Example:
a = 10, b = 20, c = 20
condition1: a < b
condition2: b > c
if(condition1 || condition2)
d = a+b+c
// Since one of the condition is true
d = 50.

// Java code to illustrate
// logical OR operator
import java.io.*;
class Logical {
public static void main(String[] args)
{
// initializing variables
int a = 10, b = 1, c = 10, d = 30;
// Displaying a, b, c
System.out.println("Var1 = " + a);
System.out.println("Var2 = " + b);
System.out.println("Var3 = " + c);
System.out.println("Var4 = " + d);
// using logical OR to verify
// two constraints
if (a > b || c == d)
System.out.println("One or both"
+ " the conditions are true");
else
System.out.println("Both the"
+ " conditions are false");
}
}
Output:
Var1 = 10
Var2 = 1
Var3 = 10
Var4 = 30
One or both the conditions are true
'Logical NOT' Operator(!): Unlike the previous two, this is a unary operator and returns true when the condition under consideration is not satisfied or is a false condition. Basically, if the condition is false, the operation returns true and when the condition is true, the operation returns false.
Syntax:
!(condition)
Example:
a = 10, b = 20
!(a<b) // returns false
!(a>b) // returns true

class Logical {
public static void main(String[] args)
{
// initializing variables
int a = 10, b = 1;
// Displaying a, b, c
System.out.println("Var1 = " + a);
System.out.println("Var2 = " + b);
// Using logical NOT operator
System.out.println("!(a < b) = " + !(a < b));
System.out.println("!(a > b) = " + !(a > b));
}
}
Output:
Var1 = 10
Var2 = 1
!(a < b) = true
!(a > b) = false
