在Java中将Chars转换为Ints

char[] chars = {'1', '2', '3'};
int[] ints = new int[chars.length];
for (int i = 0; i< chars.length; i++) {
    ints[i] = Integer.parseInt(String.valueOf(chars[i]));
}

char[] chars = {'1', '2', '3'};
int[] ints = new int[chars.length];
for (int i = 0; i< chars.length; i++) {
    ints[i] = Character.getNumericValue(chars[i]);
}
