Question

Consider the following code:

String major = "Computer Science";

What is returned by the method call
major.substring(1, 2)?

Answer 1

The method call major.substring(1, 2) in Java will return the single character 'o', as it extracts the string starting at index 1 up to, but not including, index 2.

Step-by-step explanation:

The question refers to a method call of the substring method on a Java String object. In Java, when you call major.substring(1, 2), you are asking for a part of the String starting at index 1 and ending right before index 2. In Java, string indices start at 0, so index 1 corresponds to the second character in the string "Computer Science", which is 'o'. Since the ending index is 2, and the substring method goes up to but does not include the character at the ending index, the method will return a string containing only the character at index 1. Therefore, the method call of major.substring(1, 2) will return the single character 'o'.

The method call major.substring(1, 2) will return the second character of the string major. In this case, it will return the letter 'o'.The method call major.substring(1, 2) in Java will return the single character 'o', as it extracts the string starting at index 1 up to, but not including, index 2.
