简单的System.out打印

Question

Ok guys I have this problem how do I code this but without empty line between

x

xy

xxy

xxyy

xxxyy

xxxyyy

Here is my code so far

public static void main(String[] args) {

    System.out.print("x");
    for(int i = 0;i<6;i++){

        for(int j = 0;j<i;j++){
            System.out.print("x");
        }
        System.out.println();
    }

}

Answer 1

The pattern is as follows:

1x, 0y

1x, 1y

2x, 1y

2x, 2y...

So your loop should look something like this:

int xCount = 0;
int yCount = 0;
int total = 3;
do {
    if (xCount == yCount) xCount++;
    else yCount++;
    for (int x = 0; x < xCount; x++) System.out.print("x");
    for (int y = 0; y < yCount; y++) System.out.print("y");
    System.out.println();
 } while (yCount < total);
