Core Java Programming Course- String (Cut) Slice Operations

This video tutorial covers string slice operations, including retrieving characters using indices, handling exceptions, reversing strings, extracting substrings, and splitting strings using delimiters. It provides practical exercises and examples to illustrate these concepts, making it a useful resource for understanding string manipulation in programming.

What happens if you try to access a character at an index that is out of the string's boundaries?

• The program returns null.

• The program continues without any error.

• The program throws a StringIndexOutOfBoundsException.

• The program returns the last character.

Which method is used to access a character at a specific index in a string?

• string.charAt()

• string.indexOf()

• string.substring()

• string.split()

What is the first step in reversing a string programmatically?

• Concatenate the string with itself.

• Initialize a counter to the length of the string.

• Extract each character and concatenate in reverse order.

• Use the split method to divide the string.

In the context of reversing a string, what is the role of the temporary string?

• It stores the original string.

• It is used to store the indices of characters.

• It holds the reversed string as it is built.

• It is used to count the number of characters.

What does the substring method return when only a begin index is provided?

• The first character of the string.

• An empty string.

• The string from the begin index to the end.

• The entire string from the beginning.

When using the substring method with both begin and end indices, which index is inclusive?

• Both begin and end indices are inclusive.

• Neither index is inclusive.

• Only the end index is inclusive.

• Only the begin index is inclusive.

What is the result of splitting a string using a delimiter?

• A string with all characters in uppercase.

• A reversed version of the original string.

• An array of strings divided at each delimiter.

• A single string with delimiters removed.

If a string is split using a delimiter that appears once, how many pieces will the resulting array contain?

• Four pieces

• Three pieces

• Two pieces

• One piece

What happens to the delimiter when a string is split?

• It becomes part of the first piece.

• It is included in all pieces.

• It is removed from the resulting pieces.

• It is added to the end of the last piece.

Which of the following is NOT a string operation discussed in the session?

• toUpperCase

• split

• charAt

• substring
