wish help you to fix your issue Hi I'm trying to figure out how to use BubbleSort in Java and my code is erroring and I don't know why
code :
arr.get(j) = arr.get(j+1);
arr.get(j+1) = temp; 
arr.set(j, arr.get(j+1));
arr.set(j+1, temp);
Collections.swap(arr, j, j+1);

To fix this issue I am trying to create a bubble sort program for a small presentation that I am doing. The code runs fine but the largest integer in my array is never displayed. Output for the program as it stands is:
code :
for(int i=0; i<number.length-1; i++){
//                            no '-1'
//                              V
for(int i = 0; i < number.length; i++) {
0, 1, 2, 3, 4

C Bubble Sort Integer Array - Output Issue

I hope this helps . I think the error is that your last line in your file does not have a end of line character so it reads upto end of file and when it print the same line it does not move to next line so either go to last line in your text file and put a endl in the last line or print a endl manually for each line. Another or more generic way would be to remove new line from your input, that can be done like this, while reading text do this
code :
int len = strlen(states[i]);
if(len>0 && states[i][len-1] == '\n')
    states[i][len-1] = '\0';

What is wrong in my bubble sort using ArrayList?

may help you . Your swapping code block looked like it was outside of loop, so the only one swap occurred for one iteration of main loop. You are also doing unnecessary comparing of elements, starting your inner loop with precondition j = 1. You should start it from i, as after some iterations of outer loop range from 0 to i will be already sorted.
I think you can use a simpler approach.
code :
for (int i = 0; i < ar.size() - 1; i++) {
    for (int j = i; j < ar.size(); j++) {
        if (ar.get(j) < ar.get(i)) {
            Integer temp = ar.get(j);
            ar.set(j, ar.get(i));
            ar.set(i, temp);
