How do I take specific characters in a string and uppercase them? -- Java

Question

For this program, I have to read full names in from a .txt file and capitalize the first letter of the first name and the first letter of the surname.

Ex. john brown ----> John Brown

The program must also concatenate the results so that

John Brown -----> JNBN

How would I go about doing this? I have no clue how to do this. I'm brand new to Java.

where is your sample input? Is it one name per line? Have you tried this yourself? If so, where are you stuck? — austin wernli, Feb 06 '15 at 16:12
What did you try? Also what is the rule for John Brown -----> JNBN (first/last ?) — , Feb 06 '15 at 16:12

toUpperCase() reads in files, and does the things he listed in his question? – austin wernli Feb 06 '15 at 16:14
@austinwernli - I think they were not providing the total solution but rather a direction to look at – Ascalonian Feb 06 '15 at 16:14
he didn't tell what toUpperCase() so technically maybe ;) – Feb 06 '15 at 16:15
lol you got me there @RC... Well played! Looking at this though, this does solve the question in the title. I apologize for jumping at giving this a minus 1 – austin wernli Feb 06 '15 at 16:16
