String 构造函数

public class Main {    public static void main(String[] args)    {        //能将ascii值的byte数组 转换成字符串        byte[] arr={65,66,67,68,98,99,100};        String s1=new String(arr);        System.out.println("Byte数组转字符串:"+s1);        //字符数组转字符串        char[] chars={'a','b','c','D','E','F'};        String s2=new String(chars);        String s3=new String(chars,1,4);        System.out.println("字符数组转字符串:"+s2);        System.out.println("字符数组转字符串（截取一部分）:"+s3);    }}
