changing letters in strings

[dienesh77]

How can I replace all the vowels in a string by 2 characters higher than the original( i.e. 'a' is replaced by 'c', and 'e' replaced by 'g'.... etc.) Using if/else statements. much help appreciated thanks.

You can add numbers to a character, so if you have char 'a' and add 2 it should produces char 'c'. So you just need to use if statements to check if an item is a vowel and change if it is.

how can I do this in a string?

[sunde887]

string.charAt(index)

for example

String hi = "hi";
hi.charAt(0); //'h'
hi.charAt(1); // 'i'

[dienesh77]

well in my case since the user input a string, would i use a counter to go through the string to find the vowels? if so how can i tell the counter when it reaches the end of the string?

[sunde887]

Do you know how to use for loops yet?

Use the String.length() method for this. Something like,

        String s = "test";
	for (int i = 0; i < s.length(); i++) {
	// Your logic
	}

Have you read the API documentation for the String class? It has methods that can replace parts of a String.
