Question

java中，若有int变量12345，如何转换成string 类型数组["1","2","3","4","5"]

说错了，是int类型数组

Answer 1

12345转换成字符String类型，然后截取字符串，再插入到字符数组

Answer 2

public class Test {

	public static void main(String[] args) {
		int a = 12345;
		String s = Integer.toString(a);
		String[] str = new String[s.length()];
		for(int i = 0; i < s.length(); i++){
			str[i] = s.substring(i, i+1);
			System.out.println(str[i]);
		}
	}
}

Answer 3

int a = 12345;
String a1 = a+"";
int count = a1.length();
int t = 1;
int []b = new int [count];
for(int i = 0; i < count; i++){

b[i] = Integer.valueOf(String.valueOf(a1.charAt(i)));
}
for(int j = 0; j < b.length; j++){
System.out.println(b[j]);
}
}

Answer 4

for循环 吧int数组放到String数组里面

Answer 5

直接
str[0] = i[0]+"";
