java常用api模块String类是重中之中，现总结一下其构造方法：
//1，无参
  String aa = new String();
//2，用byte[] 数组参数赋值
  byte[] b = {67,78,53,78,78,90,33};
  String a = new String(b);
  System.out.println(a);
//3，用byte[] 数组对象加索引，加长度赋值
       String a1 = new String(b,4,2);
       System.out.println(a1);
//4，用char[] 数组对象赋值，包括用索引和长度赋值
       char[] c = {'你','s','e','e','鬼'};
       String c1 = new String(c);
       String c2 = new String(c,1,2);
       System.out.println(c1+"****"+c2);
//5，用String str 做参数new对象
       String d = new String("jksahdfjkshf");
//6，直接赋值
       String e = "asdsf";
       System.out.println(d+"*****"+e);
