public class Test {
public static void main(String[] args) {
String str = "ABCDEFGHIJKLMNOPQRST";
int index = 0;
for (int i = 0; i < 8; i++) {
int sum = (int)Math.abs(i-3.5);
printTab(sum);
for (int j=0;j<4-sum;j++) {
System.out.print(str.charAt(index)+" ");
index += 1;
}
System.out.println();
}
}

private static void printTab(int sum) {
for (int i = 0; i < sum; i++) {
System.out.print(" ");
}
}
}
