Java string strings and Unicode characters convert code to each other _java

After the Java environment is installed, the JDK's Bin directory has a native2ascii.exe that can achieve similar functions, but it can also achieve the same functionality through Java code.

String Conversion Unicode Java method code fragment:

Copy Code code as follows:

/**
* String Conversion Unicode
*/
public static string String2unicode (String string) {

StringBuffer Unicode = new StringBuffer ();

for (int i = 0; i < string.length (); i++) {

Remove each character
char C = String.charat (i);

Convert to Unicode
Unicode.append ("\\u" + integer.tohexstring (c));
}

return unicode.tostring ();
}

Unicode conversion string Java method code fragment:

Copy Code code as follows:

/**
* Unicode Spin string
*/
public static string Unicode2string (string Unicode) {

StringBuffer string = new StringBuffer ();

string[] hex = Unicode.split (" \\\\u");

for (int i = 1; i < hex.length; i++) {

Convert every code point
int data = Integer.parseint (Hex[i], 16);

Append As String
String.append ((char) data);
}

return string.tostring ();
}

Test Java Code Snippets:

Copy code code as follows:

public static void Main (string[] args) {
    String test = "Most code Web site address: Www.zuidaim A.com ";
 
    String Unicode = string2unicode (test);
    
    String string = Unicode2string (Unicode);
    
    System.out.println (Unicode);
    
    System.out.println (string);
 
}

Output:

\u6700\u4ee3\u7801\u7f51\u7ad9\u5730\u5740\u3a\u77\u77\u77\u2e \U7A\U75\U69\U64\U61\U69\U6D\U61\U2E\U63\U6F\U6D
