如何通过单击按钮将单独的字符串添加到数组并通过单击不同的按钮从数组中删除字符串？

Question

I am wondering how to add strings to an array from a button click, this is what I have so far but only one text value is written to the array the rest are empty

private void addTeamButtonActionPerformed(java.awt.event.ActionEvent evt) {                                              
   String teamArray []=new String[5];

teamArray[0]= addTeamText.getText();
addTeamText.setText("");
teamArray[1]= addTeamText.getText();
addTeamText.setText("");
teamArray[2]= addTeamText.getText();
addTeamText.setText("");
teamArray[3]= addTeamText.getText();
addTeamText.setText("");
teamArray[4]= addTeamText.getText();

What I want to do is add multiple teams to a list and then be able to delete them from the array with a button called say "deleteTeamButton" if anybody has any pointers on how to implement this i would be very grateful?

Answer 1

As you just said, you only need to initialize an array list and add items in your on click function.

ArrayList<String> Teams = new ArrayList<>();

private void addTeamButtonActionPerformed(java.awt.event.ActionEvent evt) {                                              
String Team = addTeamText.getText(); 
System.out.println (Team);
Teams.add(Team);
addTeamText.setText("");

}

The same for the function that deletes items. You can look for ArrayList documentation for the deletion process.
