How to print multi-digit numbers like a 7-segment display

I am just wondering whether is it possible to display in digital format.
In this we are accepting number from console.

For example:

123 should be display in following format, and in one line.
   _  _
 | _| _|
 | |_ _|
 

I tried using switch case but not got appropriate method

"arg" is char array;
 char c;
 for(i=0;i<3;i++)
 {
 c=arg[i];
 switch(char)
 {
 
     case '1' : System.out.println("|");
                System.out.println("|");
                break;
     case '2' : System.out.println("-");
                System.out.println(" "+"|");
                System.out.println("-");
                System.out.println("|");
                System.out.println("-");
                break;
 
   same for all digit
 }
 }
 

I know this is not a correct solution to display.

Is it any alternative for this using java.
