如何將字符串轉換爲具有相同內容的字節[]

Question

我想將字符串轉換爲具有相同內容的字節[]。示例 我有：

String str = "abc"; 
byte[] bytes; 
//I want to convert "str" to "bytes" that they have same content: 
(code here) 
//after, print bytes -> "abc". 

Answer 1

只要付出一點努力，您就會達到此目的。

所以我們要做的是使用getBytes方法

byte[] convertToBytes= stuff.getBytes("UTF-8"); 
String newString = new String(convertToBytes, "UTF-8");

Answer 2

 String str = "abc"; 
     byte bytes[] = str.getBytes(); // Get the byte array 
     for (byte b : bytes) { 
      System.out.println("Byte is "+b); //Iterate and print 
     } 
     str = new String(bytes); // Create String from byte array 
     System.out.println("String is "+str);
