Answer:
4 is the correct answer for the above question.
Explanation:
- If the if-else sequence has 4 blocks then it will be designed like if, else-if, else-if and then else which made 4 blocks which are as follows:-
- The first block is an if block.
- Then the second block is an else-if block.
- The third block is also else-if block and
- The fourth block else blocks.
- So there is a need of 4 value (one value for each case) to test the application which is defined in the above scenario.
- It is because when the first if statement is false then the first else-if statement is executed and when the first else statement is false then the second else-if statement is executed and when it is false then the else statement will executed.
Answer:
I believe you want a subclass so here it is!
public class ReadWrite extends ReadOnly {
public ReadWrite(int initialValue){
super(initialValue);
}
private boolean modified = false;
public void setVal(int x) {
val = x;
modified = true;
}
public boolean isDirty() {
return modified;
}
}

Answer:
B - array; hash
Explanation:
Arrays store elements of the same data type in a list. Every element in the array is assigned a unique integer (starting at 0). You are able to access/process an element by using its assigned integer. Hashes are similar in the fact that they also store data. The difference is that each element is assigned an object type (instead of an integer), making it a collection of key pairs, as such you would typically not use this to process elements efficiently.
