Given the following sequence of Java code: int var1 = 0b0001; int var2 = 0b1111; int results1 = var1 & var2; int results2 = var1 | var2; int results3 = var1 ^ var2; int printit = results1 + results2 + results3; What are the values for results1, results2, results3 and printit after executing the code?

results1 = 1

results2 = 15

results3 = 14

printit = 30

Explanation:

public class HelloWorld{

public static void main (String []args)

int var1 = 0b0001;

int var2 = 0b1111;

int results1 = var1 & var2;

int results2 = var1

}

Output:

$javac HelloWorld. java

$java - Xmx128M - Xms16M HelloWorld

1 15 14 30

In this program we are performing binary operations with logical gates and binary numbers, to understand the result see each binary operation:

var1 & var2: refers to the AND gate, since 0001 & 1111 is 0001 our result as an integer is 1 var1 | var2: refers to the OR gate, since 0001 | 1111 is 1111 our result as an integer is 15 var1 ^ var2: refers to the XOR gate, since 0001 ^ 1111 is 1110 our result as an integer is 14 results1 + results2 + results3: refers to the sum of 3 integers, 1+15+14 equal 30
