java - Java 内存不足异常堆空间

Question

我在java中编写了读取一个excel文件并在加密数据后再次写入的代码。代码工作正常但是当我传递 12 mb 大小的文件来编码它的给出错误

 Warning:  Usage of a local non-builtin name

Exception in thread "main" java.lang.OutOfMemoryError: Java heap space at jxl.read.biff.File.next(File.java:181) at jxl.read.biff.SheetReader.read(SheetReader.java:375) at jxl.read.biff.SheetImpl.readSheet(SheetImpl.java:716) at jxl.read.biff.WorkbookParser.getSheet(WorkbookParser.java:257) at ReadExcel.read(ReadExcel.java:41) at ReadExcel.main(ReadExcel.java:162)
