Java语言中,如何将String转化成Int数组

Answer 1

/**
* 将字符串转化为int数组
*
* @param str 带解析的字符串
* @return 转化而成的int数组
*/
public int[] parse(String str) {
int length = str.length();
int[] result = new int[length];
// 依次取得字符串中的每一个字符，并将其转化为数字，放进int数组中
for (int i = 0; i < length; i++) {
char c = str.charAt(i);
result[i] = Character.getNumericValue(c);
}
return result;
}

Answer 2

String a = "1";
Integer b = Integer.parseInt(a);
System.out.println(b);

Answer 3

public class ParseString {

public static int[] stringToInts(String s){
int[] n = new int[s.length()];
for(int i = 0;i<s.length();i++){
n[i] = Integer.parseInt(s.substring(i,i+1));
}
return n;
}
public static void main(String[] args){
int[] a = stringToInts("123456");
for(int i = 0;i<a.length;i++){
System.out.println("数组中第"+i+"个数为"+a[i]);
}
}
}
