「java」java.util.Properties.load(InputStream inStream)の使い方

2017年6月3日

Javaコード
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;

import java.util.Properties;

public class ProplistDemo {

public static void main(String[] args) {
Properties prop = new Properties();
String s = “Name=sato";
String s2 = “Age=25";

try {

// create a new input and output stream
@SuppressWarnings(“resource")
FileOutputStream fos = new FileOutputStream(“properties.txt");
FileInputStream fis = new FileInputStream(“properties.txt");

// write the first property in the output stream file
fos.write(s.getBytes());

// change the line between the two properties
fos.write(“\n".getBytes());

// write next property
fos.write(s2.getBytes());

// load from input stream
prop.load(fis);

// print the properties list from System.out
prop.list(System.out);

} catch (IOException ex) {
ex.printStackTrace();
}

}
}
実行結果
— listing properties —
Name=yamada
Age=25
