java - how to find i of a token in an array[i] -

so, i've found word in document , print line in word present this:

say example file contains : "the quick brown fox jumps on lazy dog.jackdaws love big sphinx of quartz."

 fileinputstream fstream = new fileinputstream(file);         bufferedreader br = new bufferedreader(new inputstreamreader(fstream));         string strline;                 //read file line line         while((strline = br.readline()) != null){                             //check see whether testword occurs @ least once in line of text             check = strline.tolowercase().contains(testword.tolowercase());              if(check){                                     //get line, , parse words string array                 string[] linewords = strline.split("\\s+");                   for(int i=0;i<linewords.length;i++){                     system.out.print(linewords[i]+ ' ');                  } 

and if search 'fox' , linewords[] contain tokens first sentence. , linewords[3] = fox. print color of fox, need linewords[2]. wondering how can 'i' of token in linewords[i], because want output linewords[i-1]

that can done traversing array , when word , print 1 before it.here's how:-

if(linewords[0].equals(testword) return;//no preceding word     for(int i=1;i<linewords.length;i++){     if(linewords[i].equals(testword){     system.out.println(linewords[i-1]);     break;     }    }
