如何使用10-99的1000个随机数格式化数组？

Question

这可以在一行上打印数字，但我想格式化数组，以便每行有20个数字。我该怎么做呢？

Random r = new Random();

int[] myArray = new int[1000];        
for (int counter = 0; counter < myArray.length; counter++) {
    int store = 10 + r.nextInt(89);
    myArray[counter] = store;
    System.out.print(myArray[counter]);
}

Answer 1

Random r = new Random();

int[] myArray = new int[1000];        
for (int counter = 0; counter < myArray.length; counter++) {
    int store = 10 + r.nextInt(89);
    myArray[counter] = store;
    if(counter != 0 && counter % 20 == 0)
        System.out.print("\n");
    System.out.print(myArray[counter] + " ");
}
