Java Read configuration file

Java read files can be used with byte stream and character stream. Since a Chinese character accounts for two bytes, if there is a Chinese character in the configuration file, it will be garbled if it is read with a byte stream. Character streams are not garbled.

The configuration file B.properties file is as follows:

family\ name = Zhou
Second name = Dingzhao
Gender = Male
Tel No. = +86 (-) 13913462
Salary = 0.001k
Professional =java & Engineer

The code to read the configuration file is as follows:

Properties Pro = new properties ();

try {

FileReader in2 = new FileReader (The new File ("i:\\workspaces\\mywork\\xcserver\\src\\com\\xiaocong\\user\\service\\ B.properties "));

Pro.load (in2);

System.out.println (Pro.getproperty ("family name"));

Iterator<string> it=pro.stringpropertynames (). Iterator ();
while (It.hasnext ()) {
String Key=it.next ();
System.out.println (key+ ":" +pro.getproperty (key));
}

In2.close ();

} catch (FileNotFoundException e) {

E.printstacktrace ();

}

System.out.println (Pro.getproperty ("occupation"));

Output:

Zhou
Second:name = Dingzhao
Tel:no. = +86 (-) 139133462
Family Name:zhou
Gender:male
salary:0.001k
Occupation: Java & Engineer

Java & Engineers

Note:

1, there are spaces in the configuration file, you need to use the \ Escape character.

2, Pro.getproperty ("occupation") GetProperty (key) method can get the value of the variable in the configuration file.
