TJ04_02. What is the output of the following program?

public class Ex4_2{

public static void zoop() {

baffle();

System.out.print("you foo ");

baffle(); }

public static void main(String[] args) {

System.out.print("No, I ");

zoop();

System.out.print("I ");

baffle(); }

public static void baffle() {

System.out.print("baz");

ping(); }

public static void ping() {

System.out.println(".");

baffle(); } }

TJ04_03. Choose what would be the correct first line of a method named zool that takes three parameters: an int and two Strings.

TJ04_04. Identify the line of code that calls a method named zool, that takes three parameters: an int and two Strings, passing as arguments the value 11, the String "hello" and the String "world".

TJ04_06. Suppose you have a static method called printAmerican that takes the month (e.g. "July"), day (e.g. 23), year (e.g. 2018), and day of the week (e.g. "Thursday") as parameters and displays them in American format (e.g. Thursday, July 23, 2018).  Which one of the following programs calls the method correctly to print the date.

TJ04_07. in the following code the print statements  are numbered (the numbers look like //1, //2, //3, //4)

list the numbers in the order in which they are executed.

public class foo{
    public static void main(String[] args) {
        zippo("foo");
        System.out.println("foo");//1
        baffle("zoo");
    }
    public static void baffle(String blimp) {
        System.out.println(blimp);//2
    }
    public static void zippo(String quince) {
        System.out.println(quince);//3
        System.out.println(quince);//4
    }
}

TJ04_08. in order to use the Math class you must first import the package that contains it.

TJ04_09. One of the methods of the class Math is called atan.

TJ04_11. The largest possible long is 922,337,203,685

how much is 2 multiplied by itself 20 times?

TJ04_13.  each class can have only one method

TJ04_14. what is a reason to use methods

TJ04_16. what is printed by this program

class foo{
    public static void zonk(String st1, String st2, String st3){
        System.out.print(st3 + " " + st1 + " " + st2 + "\n");
    }

    public static void main(String[] args) {
        zonk("this","method has","three arguments");
    }
}

TJ04_17. the print statements of this program have been numbered (\\1,\\2,\\3,\\4).  In what order are they executed

class foo{
    public static void zonk1(String st){
        System.out.print(st);//1
    }
    public static void zonk2(String st){
        System.out.print(st);//2
    }
    public static void zonk3(String st){
        System.out.print(st);//3
    }

    public static void main(String[] args) {
        zonk2("foo");
        zonk3("foo");
        zonk1("foo");
        System.out.println();//4
    }
}

TJ04_18. Suppose we have a method mm(int x).

that contains only the following statement:

x = 5;

what is printed if the main method has the following statements:

        int x = 10;

        mm(x);
        System.out.println(x);

TJ04_19. Suppose we have a method mm(int y).

that contains only the following statement:

System.out.print(x);

what is printed if the main method only has the following statements:

        int x = 10;

        mm(x);
        System.out.println(x);

TJ04_21.  

Suppose a class has the following method:

    public static void printTime(int x) {
        hour = 3*hour;
        System.out.print(hour);
    }

if the main method of the class contains the following code:

    public static void main(String[] args) {
        int hour = 1;
        printTime(hour);
        System.out.println(hour);
    }

what would the main method print when it is executed.

TJ04_22. Javadoc 

TJ04_24. Consider following code.  In what order are the methods executed?

public class TJ04_24 {
    public static void A(){
        D();
        G();
    }
    public static void B(){
    }
    public static void C(){
        B();
        F();
    }
    public static void D(){
    }
    public static void E(){
        A();
        C();
    }
    public static void F(){
        D();
    }
    public static void G(){
        B();
    }
    public static void main(String[] args) {
        E();
    }
}
