Question

The String method substring returns ________.

a. a char
b. a String
c. void
d. a char[]

Answer 1

The String method substring returns a String. It is used to extract a portion of a string by specifying the start and optionally the end index, creating a new string.

Step-by-step explanation:

The String method substring returns b. a String. This method is used in many programming languages, including Java, and it is designed to extract a portion of a string. Given the starting index and optionally the ending index, substring creates a new string that contains the characters from the original string within the specified range.

For example, if we have a string String text = "Hello World"; and we use the method text.substring(0, 5), it will return the string "Hello". This subset includes the characters from index 0 to index 4 (the character at index 5 is not included)
