java里面String字符串和其他类型转换

本文地址:

1 byte数组和String字符串

1-1 string 转 byte[]

String str = "Hello";
byte[] srtbyte = str.getBytes();

1-2 byte[] 转 string

byte[] srtbyte;
String res = new String(srtbyte);
system.out.println(res);

1-3 设定编码方式相互转换

String str = "hello";
byte[] srtbyte = null;
try {
    srtbyte = str.getBytes("UTF-8");
    String res = new String(srtbyte,"UTF-8");
    System.out.println(res);
} catch (UnsupportedEncodingException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
