Converting an integer into an int array in Java
提问by Ron
I am very new to Java programming and was wondering if there is a way to convert an integer into an int array. The reason I ask is because I know it is possible to convert an integer into a String so I was hoping there was other shortcuts for me to learn as well.
我对 Java 编程很陌生，想知道是否有办法将整数转换为 int 数组。我问的原因是因为我知道可以将整数转换为字符串，所以我希望还有其他快捷方式可供我学习。
An example of what I am trying to do is taking int 10382 and turning it into int array {1, 0, 3, 8, 2}
我想要做的一个例子是将 int 10382 转换为 int array {1, 0, 3, 8, 2}
Any help or guidance will be much appreciated, thank you very much.
任何帮助或指导将不胜感激，非常感谢。

You can convert entire string and then you get the toCharArraymethod separately characters in an array
您可以转换整个字符串，然后toCharArray在数组中分别获取该方法的字符
Scanner t = new Scanner(System.in);
int x = t.nextInt();
char[] xd = String.valueOf(x).toCharArray();
for (int i = 0; i < xd.length; i++) {
System.out.println(xd[i]);
}
Another way of doing this would be:
另一种方法是：
int test = 12345;
int[] testArray = new int[String.valueOf(test).length()];
And then looping over it.
然后循环过去。

int x = 10382;
String[] str1 = Integer.toString(x).split("");
for(int i=0;i<str1.length;i++){
System.out.println(str1[i]);
}
