In JAVA given an array of string {"Bob hi my name is bob", "Jess hi my name is jess", "Sam hello my name is sam", "Bob hi im bob"}

I want to do make it look like this

1. take the first word of each string in the array and make it the key in a dict (hashMap) (if the key repeats then append the two strings into one)

2. get the count occurrence of each word in the string

So it looks like

{'Bob": 'hi:2 , my:1, name:1, is:1, im:1, bob:2'}

{'Jess': 'hi:1 , my:1, name:1, is:1, jess:1'}

{'Sam': 'hi:1 , my:1, name:1, is:1, sam:1'}
