Sample Solution:
Java Code:
public class Main {
public static void main(String[] args) {
String p1 = "* * * * * * ==================================\n * * * * * ==================================";
String p2 = "==============================================";
for (int i = 0; i < 4; i++) {
System.out.println(p1);
}
System.out.println("* * * * * * ==================================");
for (int i = 0; i < 6; i++) {
System.out.println(p2);
}
}
}
Output:

Java: Tips of the Day
How to convert a char array back to a string?
char[] a = {'h', 'e', 'l', 'l', 'o', ' ', 'w', 'o', 'r', 'l', 'd'}; String b = new String(a);
Note however, that this is a very unusual situation: Because String is handled specially in Java, even "foo" is actually a String. So the need for splitting a String into individual chars and join them back is not required in normal code.
