Java将单词的txt列表相互连接

Question

I am looking for the most efficient way to combine strings with one another from a list, I have around 2,000 words within a txt file that I read in and store within an arraylist, I then perform transformations on each of the words....I am now looking for a way to loop through the arraylist and perform all possible combinations of words (combining each word with every other word testing if it is correct then try another). So each concatenation will be two words, then try another two words....etc until all combinations are completed.

Answer 1

I would use a nested foreach loop:

for(String one : list){
    for(String two : list){
        //...
    }
}

and concatenate one and two in both loops.
