Question

Given that:

String wt = "TELL ME WHEN WILL YOU COME?";

String wu = wt.replace('E', 'A'); 

How many replacements will take place?

Options

• 4

• 3

• 2

• 1

Answer 1

4

Explanation:

• The replace('E', 'A') method scans the entire string from left to right and substitutes every single occurrence of the character 'E' with the character 'A'.
• By looking at the string "T**E**LL M**E** WH**E**N WILL YOU COM**E**?", we can see that the letter 'E' appears exactly four times, meaning four individual character replacements will take place.
