Question

Assume the following variables have been declared:

word is a String variable that has been declared and assigned a value
result is a String variable that has been declared
n is an int variable that has been declared and assigned a value
Write a statement that gets the first n characters of word as a substring and assigns the substring to the result variable.
For example, if the value of word were "dystopia" and the value of n were 3, the statement would assign "dys" to result.

Answer 1

You can achieve this in Java using the substring method. Here's how you can write the statement to get the first n characters of the word and assign them to the result variable:

result = word.substring(0, n);

In this statement, word.substring(0, n) will create a substring of word starting from index 0 (the beginning) and ending at index n-1, effectively extracting the first n characters from word and assigning them to result.
