如何在java中将字节数组转换为字符串 [英] How to convert byte array to string in java

问题描述

我有这样的代码：

  byte  [] b =  new   byte  [ 5 ]; 
 b [ 0 ] =  97 ; 
 b [ 1 ] = -68; 
 b [ 3 ] =  4 ; 
 
 
系统。 out  .println（b， < span class =code-string> ISO-8859-1）; 
 
 此  不打印任何内容 for   4 。 
 
在Linux中，它的显示框;请尽快帮助。 
 
 我尝试过： 
 
系统。 out  .println（b，   ISO-8859-1）; 
这已经  -68;但不是   4 ; 

解决方案

代码点4不是可打印字符，而是控制字符。由实现来定义打印的内容（没有任何东西，一个像空格或盒子一样的地方，或以某种方式解释它）。

I have code like this:

byte[] b = new byte[5];
    b[0] = 97;
    b[1] = -68;
    b[3] = 4;


System.out.println (b, "ISO-8859-1");

this is not printing anything for 4.

In Linux, its showing boxes; Please help ASAP.

What I have tried:

System.out.println (b, "ISO-8859-1");
 This has worked for -68; but not for 4;

解决方案

The code point 4 is not a printable character but a control character. It is up to the implementation to define what is printed (nothing, a place holding character like space or a box, or interpreting it in some way).
