Question

Implement the NOT operator in real life example. Related to java.

Answer 1

Explanation:

public class Test {

public static void main(String args[]) {

int a = 60; /* 60 = 0011 1100 */

int b = 13; /* 13 = 0000 1101 */

int c = 0;

c = a & b; /* 12 = 0000 1100 */

System.out.println("a & b = " + c );

c = a | b; /* 61 = 0011 1101 */

System.out.println("a | b = " + c );

c = a ^ b; /* 49 = 0011 0001 */

System.out.println("a ^ b = " + c );

c = ~a; /*-61 = 1100 0011 */

System.out.println("~a = " + c );

c = a << 2; /* 240 = 1111 0000 */

System.out.println("a << 2 = " + c );

c = a >> 2; /* 15 = 1111 */

System.out.println("a >> 2 = " + c );

c = a >>> 2; /* 15 = 0000 1111 */

System.out.println("a >>> 2 = " + c );

}

}

Answer 2

Answer:

=> public static void scanDouble(Scanner in) {

System.out.print("Enter a number: ");

if (!in.hasNextDouble()) {

String word = in.next();

System.err.println(word + " is not a number")

return;

}

double x = in.nextDouble();

printLogarithm(x);

}
