THIS IS IN JAVA
Given x = 1, y = 2, and z = 3, how is the expression evaluated? In the choices, items in parentheses are evaluated first.
<pre><code>(x == 5) || (y == 2) && (z == 5)</code></pre>
A. false OR (true AND false) --> false OR false --> false
B. false OR (true AND false) --> false OR true --> true
C. (false OR true) AND false --> true AND false --> false
D. (false OR true) AND false --> true AND false --> true
Create a Java program that declares and initializes two integer variables, "num1" and "num2", with values of your choice
Output the values of "num1" and "num2" to the console using the System.out.println() method.
Use the addition operator (+) to add "num1" and "num2" together and output the result to the console.
Use the subtraction operator (-) to subtract "num2" from "num1" and output the result to the console.
Use the multiplication operator (*) to multiply "num1" and "num2" together and output the result to the console.
Use the division operator (/) to divide "num1" by "num2" and output the result to the console.
Use the modulus operator (%) to find the remainder when "num1" is divided by "num2" and output the result to the console.
Use the increment operator (++) to increment the value of "num1" by 1 and output the new value to the console.
Use the decrement operator (--) to decrement the value of "num2" by 1 and output the new value to the console.
Please explain the questions below.
//8. Experiment with the below code. When would you use this data type?
// In Java "or" is represented by || and "and" is represented as &&
//boolean x = 0;
//boolean x = true;
//x = !x;
//x = x || false;
//System.out.println(x);
//9. Explain what's going on here.
//char x = 'A';
//char x = 65;
//char x = 'A'; x++;
//char x = 12;
//System.out.println("x = " + x);
