nama file bacaKeyboard.java

import java.io.*;

public class bacaKeyboard {
public static String bacaString(){
int karakter;
String str = "";
boolean selesai = false;

while (!selesai){
try{
karakter = System.in.read();
if (karakter < 0 || (char) karakter == '\n')
selesai = true;
else if ((char)karakter !='\r')
str = str + (char) karakter;
}
catch(java.io.IOException e){
System.err.println("Ada Kesalahan");
selesai = true;
}
}
return str;
}
// public bacaKeyboard() {
// }
//

}

ulang = true;
}
}


}

simpan satu folder, jangan lupa compile terlebih dahulu keduanya.. happy coding.
