Complete question is attached as snapshot.

Answer:

This will result in a compilation error.

Here's the inheritance hierarchy:

Meg -> Lois -> Brian -> Stewie

Now Meg has 2 public Fxns, a() and toString().

Lois inherits from Meg and all its public functions as well but, overrides the a() fxn of its super class.

So finally Lois has fxns a(), b() and toString().

Brian extends Lois and inherits all the above listed fxns of Lois, but overrides the b() and toString() fxns.

Stewie extends Brian and inherits all the fxns of Brian, but overrides the a() and toString() fxns.

In the Main driver fxn, we call a() and b() methods of all these classes but, the base class Meg has no b() and it is not extending any class so its not available in its scope.

This results in a compilation error.

Write a static method called bothStart that allows the user to input two Strings and returns the String that is the longest subs

marishachu [46]

Answer:

public static String bothStart(String text1, String text2){
String s = "";
if(text1.length() > text2.length()) {
for (int i = 0; i < text2.length(); i++) {
if (text1.charAt(i) == text2.charAt(i)) {
s += text1.charAt(i);
}else{
break;
}
}
return s;
}else{
for (int i = 0; i < text1.length(); i++) {
if (text1.charAt(i) == text2.charAt(i)) {
s += text1.charAt(i);
}else{
break;
}
}
return s;
}
}

Explanation:

Let's start with creating a static method bothStart() with two String type parameters, text1 & text2 (Line 1).

Create a String type variable, s, which will hold the value of the longest substring that both inputs start with the same character (Line 2).

There are two possible situation here: either text1 longer than text2 or vice versa. Hence, we need to create if-else statements to handle these two position conditions (Line 4 & Line 13).

If the length of text1 is longer than text2, the for-loop should only traverse both of strings up to the length of the text2 (Line 5). Within the for-loop, we can use charAt() method to extract individual character from the text1 & text2 and compare with each other (Line 15). If they are matched, the character should be joined with the string s (Line 16). If not, break the loop.

The program logic from (Line 14 - 20) is similar to the code segment above (Line 4 -12) except for-loop traverse up to the length of text1 .

At the end, return the s as output (Line 21).
