Q: Give the output of the following string methods: "MISSISSIPPI".indexOf('S') + "MISSISSIPPI".lastIndexOf('I')

Answer: B

Explanation:

Let's break down the two string method operations in Java for the string "MISSISSIPPI":

The indexOf('S') method returns the index of the first occurrence of the character 'S' in the string "MISSISSIPPI".

The string "MISSISSIPPI" has the following indices:


M  I  S  S  I  S  S  I  P  P  I
0  1  2  3  4  5  6  7  8  9 10

So, "MISSISSIPPI".indexOf('S') returns 2.

The lastIndexOf('I') method returns the index of the last occurrence of the character 'I' in the string "MISSISSIPPI".

So, "MISSISSIPPI".lastIndexOf('I') returns 10.

Now, adding these two results together:


indexOf('S') + lastIndexOf('I')
= 2 + 10
= 12

So, the correct answer is:
