What is the Java output? Part One: class Driver { public static void main(String[] args) { int a = 5; int b = 3; if (a < b || a * 2 < b) System.out.print(a - b); System.out.print(b + a); } } Part Two: class Driver { public static void main(String[] args) { int a = 5; int b = 8; if (a < b) if (a * 2 < b) System.out.print("foo"); else System.out.print("bar"); else System.out.print("buz"); } }
1. What is the output when you run printIn()? public static void main(String[] args) { if (true) { int num = 1; if (num > 0) { num++; } } int num = 1; addOne(num); num = num - 1 System.out.println(num); } public void addOne(int num) { num = num + 1; } 2. When creating an array for primitive data types, the default values are: a. Numeric type b. Char type c. Boolean type d. String type e. Float...
Analyze the following code: public class Test { private int t; public static void main(String[] args) { int x; System.out.println(t); } } t is non-static and it cannot be referenced in a static context in the main method. The program compiles and runs fine. The variable t is not initialized and therefore causes errors. The variable x is not initialized and therefore causes errors.
Show the output of the following piece of code: public static void main(String[] args) { char x = 'a'; char y = 'c'; System.out.println(++x); System.out.println(y++); System.out.println(x - y); }

Analyze the following code: public class Test { private int t; public static void main(String[] args) { int x; System.out.println(t); } } The variable t is private and therefore cannot be accessed in the main method. The program compiles and runs fine. t is non-static and it cannot be referenced in a static context in the main method. The variablet is not initialized and therefore causes errors. The variable x is not initialized and therefore causes errors.
