java - How to read a file and scan it -

i have been trying code java script tries read file , displays array. scrip try , read array , fine last 1 of array , locks , can try , scan file using scan function let type down code , display line on.

this example:the dat file contains these:

bob smith dre 134

smith bre 331

we use scan find determine item in dat file. scan

dre 134

and displays

bob smith dre 134

so im trying array looks [bob, smith. dre, 134]

and we're trying find array[2] , array[3] via scan.

public static void main(string[] args) throws ioexception { // todo code application logic here  // // read keywesttemp.txt  // create token1 string token1 = "";  // for-each loop calculating heat index of may - october  // create scanner infile1 scanner infile1 = new scanner(new file("d:/ltu work/eclipseworkspace/tst/src/stars1.dat")).usedelimiter(",\\s*");  // original answer used linkedlist, preferable use arraylist in cases // list<string> tempt = new linkedlist<string>(); list<string> temps = new arraylist<string>();  // while loop while (infile1.hasnext()) {   // find next line   token1 = infile1.next();   temps.add(token1); } infile1.close();  string[] tempsarray = temps.toarray(new string[0]); (string s : tempsarray) {     scanner scan = new scanner(system.in);     string pick = scan.nextline();   if (pick.equals(tempsarray[5]));   {       system.out.println("hello");   } }
