Java (add)

I'm studying Java, so I'll upload it as a memorandum.

【add】 This method is used when adding an element to ArrayList.

Put the value you want to add in the variable name .add () and use it.

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

array.add ("Japanese"); array.add ("English"); array.add ("French");

The output in the list is as follows.

System.out.println(array);

Japanese, English, French

If you continue to add after this, it will be added as follows.

array.add ("Chinese"); array.add ("German");

System.out.println(array);

Japanese, English, French, Chinese, German
