确保创建新实例:在需要保证内容不同的情况下,new String()有助于避免共享相同的字符串实例。 从字节数组生成字符串:使用new String(byte[] bytes)可以从字节数组中生成字符串。 byte[]byteArray={65,66,67};StringfromByteArray=newString(byteArray);System.out.println("从字节数组生成字符串: "+fromByteArray...
In the following example, we will take a byte array{65, 66, 67, 68}and create a new stringstrfrom this byte array. Java Program </> Copy public class Example { public static void main(String[] args) { byte arr[] = {65, 66, 67, 68}; String str = new String(arr); System.ou...
接下来分析一下常规的byte[]转为String的方法,代码如下: 1 2 3 4 5 6 7 public static String byteArrayToStr(byte[] byteArray) { if (byteArray == null) { return null; } String str = new String(byteArray); return str; } 很简单,就是String的构造方法之一。那我们分析Java中String的源码,可...
下面是将以上步骤整合在一起的完整代码示例: importjava.io.ByteArrayOutputStream;publicclassStringToByteArrayOutputStreamExample{publicstaticvoidmain(String[]args){Stringstr="Hello, World!";ByteArrayOutputStreamoutputStream=newByteArrayOutputStream();byte[]byteArray=str.getBytes();outputStream.write(byteArr...
public static void main(String[] args) { byte[] byteArray = { 'P', 'A', 'N', 'K', 'A', 'J' }; byte[] byteArray1 = { 80, 65, 78, 75, 65, 74 }; String str = new String(byteArray); String str1 = new String(byteArray1); ...
byte[] byteArray = {97,98,99}; String str3 =newString(byteArray); System.out.println("第三个字符串:"+ str3); String str4 ="Hello"; System.out.println("第四个字符串:"+ str4); } } 二、字符串常量池 字符串常量池:程序当中直接写上的双引号字符串,就在字符串常量池中, new的不在...
String charsetName="UTF-8";// 指定字符集名称,例如 UTF-8ByteArrayOutputStream baos=newByteArrayOutputStream();baos.write(data);// 假设 data 是要写入 ByteArrayOutputStream 的数据byte[]bytes=baos.toByteArray();String result=newString(bytes,charsetName);baos.close(); ...
