How do we convert a string to integer when we have a print statement and then we are going to create switch case so just before switch case we will convert the string statement to integer?

String number = "4";

You can print a string as a number or vice versa.

System.out.println("number:" number); // output - number: 4
System.out.println("number: "+4); // output - number: 4

Converting a String object into an int:

int n = Integer.parseInt(number);

// now a switch statement to do different things depending on the value

switch(n) {
case 0: // do something here if n = 0
break; 
case 1:  // etc 
}

You can use switch on char value in this way:

String key = Greenfoot.getKey();
if (key != null && key.length() == 1)
{
    switch (key.charAt(0))
    {
        case '0': ; break;
        case '1': ; break;
        case '2': ; break;
    }
}
