Hi i need help with this saml java program i just dont understand
lol umm i wanted to be able to enter a couple of con objects like

enterDouble(), enterChar(), enterString() and enterDate(). into this program.::

import tools.*;

public class ConsoleDemo {

public static void main(String[] args) {

// define and construct Console device
Console con;
con = new Console(true);

// example of entering an integer
int i;
con.prompt("Please enter an integer [0 to 10]");
i = con.enterInt();
con.display("The integer is: " + i + "\n");

// example of entering a double
con.prompt("please enter an integer [0 to 10]");
i = con.enterdouble();
con.display("The Integer is: " + i + "\n");

} // end main()
} // end class ConsoleDemo

i dont kno how to add on the above cons.

Im having priblems with tis little program im writing. Im just a beginer and im so confused lol can some one plz help me.
Here's the program. i get errors with charAt()
equals(), equalsIgnoreCase(), length(), substring(). maybe if someoen could test the program they could understand better ?it says cannot resolve symbol - method equals ().

thnxs

public class StringDemo {

public static void main(String[] args) {
