【Java】String getBytes() toCharArray()

public byte[] getBytes();//获取字节数组
public char[] toCharArray() {//获取字符数组    // Cannot use Arrays.copyOf because of class initialization order issues    char result[] = new char[value.length];    System.arraycopy(value, 0, result, 0, value.length);    return result;}

public String testString(String s) {    if (s == null)        return null;    int len = s.length();    System.out.println(s.getBytes()[2]);    System.out.println(s.toCharArray());    return null;
}
//执行结果://99//abc
