I have to print the series shown below in java:

***1***

**2*2**

*3*3*3*

4*4*4*4

My current implementation is:

public static void printSeries(int number,int numberOfCharsinEachLine){

    String s="*";

    for(int i=1;i<=number;i++){
        int countOfs=(numberOfCharsinEachLine-(i)-(i-1))/2;
        if(countOfs<0){
            System.out.println("Can't be done");
            break;
        }
        for(int j=0;j<countOfs;j++){
            System.out.print(s);
        }
        System.out.print(i);
        for(int k=1;k<i;k++){
            System.out.print(s);
            System.out.print(i);
        }

        for(int j=0;j<countOfs;j++){
            System.out.print(s);
        }
        System.out.println();
    }

}

But there are lot of for loops, so I'm wondering whether this can be done in a better way or not?
