JFrame输入到数组，输出到yml文件

Question

是否有文档或任何人可以帮助我了解如何输出通过JFrame窗口输入的数组中列出的数据？

它需要像这样进入数据字段：

#Name of the class, does not have to match the file name but is good practice.
name: [Array output 0]
#Is this the default join class?
default: [Array output 1]
#does this require a permission to be? (node.classname)
wildcard-permission: [Array output 2]
#Is this a primary or a secondary class? (primary are usually combat, secondary is crafting)
primary: [Array output 3]
#can it be a secondary?
secondary: false
#description shown in class lists.
description: The Default Starter Path
#Runs a cmd as console or not on selection of this class.
run-command:
  as-console: true
  #you can have multiple cmds run
  #use {player_name} for plugins who dont support @p, etc.
  command:
    -  [Array output]
    -  [Array output]
