我的其他方法工作正常,但是我无法弄清楚如何操作int [] x数组以获取12来替换小于12的所有数字。我可以从int [] x中获取小于12的数字以进行打印,但是我可以不能得到12来替换少于12的所有数字
最佳答案
如下所示修改replaceLessThan
方法,以替换所有小于e
的元素。
public static void replaceLessThan(int[] x, int e) {
System.out.println();
for (int counter = 0 ; counter<x.length; counter++){
if ( x[counter] < e){
x[counter] = e; // Add this line to replace elements.
}
System.out.print (x[counter] + " "); // Move this statement out of if condition
}
