用程序创建zip或rar压缩包

public static void main1(String[] args) {
		StringBuffer sb = new StringBuffer();
		for (int i = 0; i < 10000; i++) {
			sb.append("看**人物委琐,举止粗糙 \n");
		}
		try { 
																			//此处后缀可以为rar也可为zip
			ZipOutputStream out = new ZipOutputStream(new FileOutputStream("c:/abc.rar"));
			
			ZipEntry entry = new ZipEntry("abc.txt");
			
			out.putNextEntry(entry);
			
			out.write(sb.toString().getBytes());
			out.close();
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
