Question

I have a dilemma on my hands. After much trial and error, I still could not figure out this simple task.

I have one array

String [] array = {anps, anps, anps, bbo, ehllo};

I need to be able to go through the array and find duplicates and print them on the same line. Words with no duplicates should be displayed alone

The output needs to be like this

anps anps anps
bbo
ehllo

I have tried while, for loops but the logic seems impossible.

Answer 1

Sort the array first then

for(int i = 0, i < array.length; i++){
    String temp = array[i];
    System.out.print(temp+" ");
    for(int j = i+1; j < array.length; j++){
        String temp2 = array[j];
        if(temp.compareTo(temp2) == 0){
            System.out.print(temp2+" ");
            i++;
        }
    }
    System.out.println();
}

or something similar…
