The stone of an object by the current values of its ____________. Name two data

Question

The stone of an object by the current values of its ____________. Name two data types we could use if we wish to have variables that can hold numbers. _______ _______ Recall that our Class List class included a vector named "names" that held the names of students in the class. Below, write just a few lines of code that would display the last name in the list. (No need to write an entire method.) A method that simply returns some simple information about an object is called a (n) _________ method. (2) Which of the following defines a data type? (Circle answer) constructor parameter class field Which of the following would have a data type associated with them? (Circle all that apply.) constructor parameter class field True or False: A constructor never has any parameters. Circle your answer. True False True or False: Floating point calculations are always 100% accurate. True False If a method does not return a value, the word __________ appears in the method signature instead of a type name. Again consider the Class List class. Suppose you were asked to write a method named "twice" that, given a name (passed as a parameter) will return true if the name appears exactly twice in the list. Otherwise false will be returned. Below, write a complete signature (header) for the method. Write only the signature (one line).

Explanation / Answer

1) Methods

2) Int, long

3) CODE IN JAVA: according to question names is a vector contain names of students

Enumeration e=names.elements();  

while(e.hasMoreElements()){

e.nextElement();

}

System.out.println(e); //after all the while loop to print only last element(name of student)

4) toString method

5) class

6) parameter

7) False

8) False

9) Void

10) public Boolean twice(String name){}
