我正在从制表符分隔的文本文件中提取值到 groovy 中的列表中。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++
}

运行它会给我以下错误。
捕获:java.lang.ArrayIndexOutOfBoundsException:4 java.lang.ArrayIndexOutOfBoundsException:4 在 extractBeliefs$_run_closure1.doCall(extractBeliefs.groovy:19) 在 extractBeliefs.run(extractBeliefs.groovy:12)
我知道可能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 line fileContents.eachLine { line ->
,所以我无法找到出错的地方。
在这方面的任何建议都将受到高度赞赏。
