简单的读写Properties操作

写Properties

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.util.Properties;

public class WriteProperties {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		File file = new File("D://Properties.txt");
		Properties property = new Properties();
		try {
			OutputStream os = new FileOutputStream(file);
			property.setProperty("NAME", "Ben Zeph");
			property.setProperty("AGE", "23");
			property.setProperty("MAJOR", "Computer Science");
			try {
				property.store(os, "This is properties file");
				os.close();
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		System.out.println("数据写入完成");

	}

}

读Properties

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import java.util.Properties;

public class ReadProperties {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		String name = "";
		String age = "";
		String major = "";
		Properties property = new Properties();
		File file = new File("D://Properties.txt");
		try {
			InputStream  is =new FileInputStream(file);
			try {
				property.load(is);
				name = property.getProperty("NAME");
				age = property.getProperty("AGE");
				major = property.getProperty("MAJOR");
				is.close();
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		} catch (FileNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		System.out.println("NAME:"+name);
		System.out.println("AGE:"+age);
		System.out.println("MAJOR:"+major);
	}
