Combining more than one method

Question

Hi all,
I am trying to combine the below method 3 times and piece together the resulting characters (ieAAA),
Random rand = new Random();
int num = rand.nextInt(10);
char myChar = (char) ('A' + num);
System.out.println("The random string is: "+myChar);
I have tried,
Random rand = new Random();
int num1 = rand.nextInt(10);
int num2 = rand.nextInt(10);
int num3 = rand.nextInt(10);
char myChar1 = (char) ('A' + num1);
char myChar2 = (char) ('A' + num2);
char myChar3 = (char) ('A' + num3);
System.out.println("The random string is: " myChar1, myChar2, + Char3 )
Obviously does not work. Any suggestions?

well, the problem is that you are using commas in the last statement, try this:
Random rand = new Random();
int num1 = rand.nextInt(10);
int num2 = rand.nextInt(10);
int num3 = rand.nextInt(10);
char myChar1 = (char) ('A' + num1);
char myChar2 = (char) ('A' + num2);
char myChar3 = (char) ('A' + num3);
System.out.println("The random string is: " +myChar1 + myChar2 + myChar3);Or if you want, it may be:
Random rand = new Random();
String string = "";
for (int i = 1; i <= 3; i++) {
     int num = rand.nextInt(10);
     char myChar = (char) ('A' + num);
     string = string + myChar;
System.out.println("The random string is: " + string);
