// Vaike demo kasurealt stringi lugemise ja parsimise kohta
//
// Olulist tahele panna:
// - Programm loeb kasurealt yhe stringi, kus on eraldava stringiga eraldatud sonad
// - loetakse kokku eraldajad ja trykitakse nende arv valja
// - string lohutakse eraldaja jargi (vaikimisi koma, voib olla ka muu string)
// - sona alguses ja lopus olevad tyhikud visatakse ara
// - tehakse stringimassiiv ja sonad pannakse ykshaaval sinna massiivi
// - lopuks trykitakse sonad massiivist valja

// Must import java.io.* in order to get access to libraries

import java.io.*;
