i need help with this asap i did it but for horizontal $3$ where it has to print $10$ rows its printing $12$ in java my program is drawing app

public static String getHorizontalBars$($int maxRows, int maxCols, int bars, char color$1,$ char color$2,$ char color$3)-$ This method returns a

string with a number of horizontal bars that correspond to the bars parameter. To compute the size of each horizontal bar, divide maxRows

by the specified number of bars. The first horizontal bar will use color$1,$ the second color$2,$ and the third color$3.$ If more than $3$ bars are

present, we will start again with color$1.$ If the computed size for a horizontal bar is less than $1,$ or any of the colors is invalid, the method will

return null and no diagram will be generated. The method MUST NOT rely on System.out.println$().$ For example, calling

DrawingApp.getHorizontalBars$(12,10,3,\text{'}$R$\text{'},\text{'}$G$\text{'},\text{'}$B$\text{'})$; will return the following string:

Calling DrawingApp.getHorizontalBars$(6,8,3,\text{'}$R$\text{'},\text{'}$B$\text{'},\text{'}$G$\text{'})$; will return the string:
