当我运行以下程序时，我收到错误：
Exception in thread "main" java.lang.NumberFormatException: For input string: "[-52.06907251530153, -90.45811476077165]"
at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
at java.lang.Integer.parseInt(Integer.java:492)
at java.lang.Integer.parseInt(Integer.java:527)
at code.readFile(code.java:31)
at code.main(code.java:22)
这个错误是什么意思？为什么会这样？
