我有一个42行的文本文件.每行包含超过22,000个以逗号分隔的数字.
我想从每一行中提取某些数字,并且我有一个长度为1000的int数组,其中包含从这42行中的每一行中需要的1,000个数字.
例如,如果数组包含43,1,3244,则意味着我需要从第一行到第42行开始的第43个数字,第1个数字和第3244个数字.
我的for循环似乎不起作用,它只读取文本文件中第一行有42行220000个数字,我不知道它出错了.
for(int i=0;i<42;i++){ //irretates through the 42 lines of
counter=1; // to keep track about on which line the code is working
System.out.println("Starting line"+i);
st2=new StringTokenizer(raf1.readLine(),",");
//raf3 is a RandomAccessFile object containing the 42 lines
a:while(st2.hasMoreTokens()){
b=is_there(array2,counter);
// is_there is a method that compares the rank of the taken being read with
//the whole array that has the 1000 numbers that i want.
if(b==false){
// if the rank or order of token [e.g. 1st, 432th] we are …
