Question

What will be the value stored in the variable 'c' if the following statement is executed? 

c = "COMPUTER".charAt("COMPUTER".indexOf('P')) 

Options

• 3

• 4

• P

• M

Answer 1

P

Explanation:

charAt(int index) returns a character from the given index of the string, and indexOf(char ch) returns the index of the first occurrence of a character in the string.
Since P is at 3^rd position so indexOf('P') will return 3 and charAt(3) function will return the character at the third index i.e., 'P'. So, the given statement is solved as follows: 

c = "COMPUTER".charAt("COMPUTER ".indexOf('P'))
c = "COMPUTER".charAt(3)
c = 'P'
