数组。lang.ArrayIndexOutofBounds异常:4
我正在groovy中致力于将值从一个选项卡分隔的文本文件提取到一个列表中。但是我遇到了ArrayIndexOutOfBoundsException
代码
println("Reading File Contents")
def fullArray = new String[31721][4]
def availableArray = new String[1386][2]
def filteredFullArray = new String[1386][5]
String fileContents = new File('beliefs.txt').text
String availableContents = new File('available.txt').text
def count = 0
fileContents.eachLine { line ->
String[] str
str = line.split('\t')
def subCount = 0
for (subCount; subCount < str.length; subCount++) {
fullArray[count][subCount] = str[subCount]
}
count++
}

运行此命令会导致以下错误
Caught: java.lang.ArrayIndexOutOfBoundsException: 4 java.lang.ArrayIndexOutOfBoundsException: 4 at extractBeliefs$_run_closure1.doCall(extractBeliefs.groovy:19) at extractBeliefs.run(extractBeliefs.groovy:12)
我知道发生上述错误的原因。但是,由于我的数组没有超过最后一个索引,并且错误显示在fileContents.eachLine { line ->
行,因此我无法找到错误所在
我们将非常感谢您在这方面提出的任何建议
# 1 楼答案
更好的方法是先用单个空格替换所有多空格或制表符,然后用单个空格分割
# 2 楼答案
您的初始错误来自此行(19):
第12行只是在异常退出闭包时提升异常。这肯定表明您在一行上有一个额外的选项卡。。。出于调试目的,在尝试将该行加载到阵列之前,请尝试将其打印到控制台。这将帮助您确定哪一行有错误

尝试用空格分割
