This

/*
Use Notepad to create a text file named fileOne.txt
which must be in the same directory that src is in
To find src, open your project in NetBeans and hover its name, which is in
the top left just below the Projects menu; this will display the path to your project
My project path is, yours will be different
I:\\Ajava\161\WPPractice\IO\charstream\chario
My fileOne.txt is located in chario
*/
Scanner getit = new Scanner( file1 );
// connect a Scanner to the file int num, square;
