hey guys,
-So in case 2, i'm trying to have the user to input elements (N,Y,P,D,G) only with specific Array location. I used switch inside a switch, but how do i re-loop if he enters wrong elements?
-in case 3, i'm trying to print the whole 2D array, but the original array is filled with the element G.
-in case 4, i'm trying to change the map view to the symbols.
Just found this as a practice, trying to learn, to some point, beginner complex programming, so any help is appreciated and any criticism is highly appreciated because i want to have a good basic knowledge of java :)
import java.util.Scanner;
public class Studyone {
public static void main(String[] args)
{
Scanner input = new Scanner(System.in);
int row;
int col;
int row1; //for case 2, so it would allow the user to input the element in the request array
int col1;
System.out.println("Enter the row: ");// knowing the row and the col of the 2D array to base the rest on.
row = input.nextInt();
System.out.println("Enter the col: ");
col = input.nextInt();
String sentence;
String sentence2;
String sentence3;
String tempelement;
String N;
String Y;
String G;
String P;
String D;
int choice;
System.out.println("The menu\n1)Enter the Elements in order\n2)Enter the the Col and row number spec.\n3)Show the Orig. map as is\n4)Show symbolic map.");
choice = input.nextInt();
System.out.println(choice);
String [][] map = new String[row][col];
switch (choice)
{
case 1:
sentence3=input.nextLine(); // for some reason it auto enters the first map [0][0] as null, this line allows the user to input the map[0][0]
map[0][0]=sentence3;
for (int i = 0; i < map.length; i++)
{
for (int j = 0;j < map[i].length; j++)
{
System.out.println("Enter the element");
sentence2 = input.nextLine();
map[i][j]=sentence2;
}
System.out.println(map[1][1]);
System.out.println(choice);
}
break;
case 2:
System.out.println("Enter the row");
row1 = input.nextInt();
System.out.println("Enter the col");
col1 = input.nextInt();
System.out.println("Enter the element you want to enter");
tempelement = input.nextLine();
switch (tempelement)
{
case "Y":
map[row1][col1] = tempelement;
case "N":
map[row1][col1] = tempelement;
case "P":
map[row1][col1] = tempelement;
case "D":
map[row1][col1] = tempelement;
case "G":
map[row1][col1] = tempelement;
}
System.out.println(tempelement); // test,does not let me enter any temp elements, lets it empty in the input without letting the use enter anything. Figure out error
System.out.println(choice); // test, prints the right choice, Correct.
break;
case 3:
for (int i=0;i > map.length;i++)
{
for (int j=0; j > map[i].length; j++)
{
map[i][j] = N;
// print statment, need to find how to do.
}
}
break;
case 4:
// having symbols instead of the letters, N=* , P= ~ , Y=. , G= #, D=@
//
}
}
}
