Answer the following statements true (T) or false (F)
1. Programming style includes techniques for consistently putting spaces and indentation in a program to help create visual cues. 2. Both character and string literals can be assigned to a char variable. 3. A variable's scope is the part of the program that has access to that variable. 4. Named constants are initialized with a value and that value cannot change during the execution of the program. 5. When you call one of the Scanner class's methods to read a primitive value, such as nextInt or nextDouble, and then call the nextLine method to read a string, an annoying and hard-to-find problem can occur.
Analyze the following code:
``` public class Test { public static void main(String[] args) { Object a1 = new A(); Object a2 = new Object(); System.out.println(a1); System.out.println(a2); } } class A { int x; @Override public String toString() { return "A's x is " + x; } }``` a. The program cannot be compiled, because System.out.println(a1) is wrong and it should be replaced by System.out.println(a1.toString()); b. When executing System.out.println(a1), the toString() method in the Object class is invoked. c. When executing System.out.println(a2), the toString() method in the Object class is invoked. d. When executing System.out.println(a1), the toString() method in the A class is invoked.
