Question

100%

Consider the class definition shown below. Notice that some lines have been replaced by descriptions (in angle brackets) of the code required. The class defines a constructor and a method named run.

Fill in the appropriate Java and then answer the questions:

A) How many variables in total are referenced by the program?

B) How many data types are used?

Applying a run method of this class will print...

<Header for a definition of a class called "Scramble">
<Declaration of a 2d String array called "words",
with initialization to {{"a","b","c"},
{"d","e","f"},{"g","h","i"}}.>
public Scramble() {
}
String[] a = words[2];
words[2][0] = words[0][2];
words [1][2] = words [2][1];
<Assignment of element at index 1 of words, to index 2
<Assignment of array a to index 1 of words>
public void run() {
for (int i = words.length-1; i >= 0; i--) {
String = "";
for (int j = 0; j < words.length; j++) {
s += words[i][j];
}
}
System.out.print(s);
<Termination of class definition>
