我正在编写一个循环,该循环将数字15分配给数组中的每个元素,而不使用任何比较运算符,例如或!=。
显然有一种使用异常处理来做到这一点的方法。
有任何想法吗?
这是我尝试过的:
public class ArrayProblem {
public static void main(String[] args) {
int[] arrayElements = {0,0,0,0,0};
boolean isValid = true;
System.out.println("Array element values before: " + arrayElements[0] + "," + arrayElements[1] + "," + arrayElements[2] + "," + arrayElements[3] + "," + arrayElements[4]);
try
{
while(isValid)
{
throw new Exception();
}
}
catch(Exception e)
{
System.out.println(e.getMessage());
}
finally
{
//finally block executes and assigns 15 to each array element
arrayElements[0] = 15;
arrayElements[1] = 15;
arrayElements[2] = 15;
arrayElements[3] = 15;
arrayElements[4] = 15;
System.out.println("New array element values are " + arrayElements[0] + "," + arrayElements[1] + "," + arrayElements[2] + "," + arrayElements[3] + "," + arrayElements[4]);
}
}
}
最佳答案
Arrays.fill(intArray, 15);
在内部,此功能可能会进行比较,但也许符合您的限制?
如果解决方案需要循环,则这是没有直接比较的另一种方式:
int[] array = new int[10];
int arrIdx = -1;
for (int i : array){
arrIdx++;
array[arrIdx]=15;
System.out.println(array[arrIdx]);
}
