map的遍历

public static void main(String[] args) {
	<String,String> m = new HashMap<String, String>();
		
	m.put("gdsad", "sddas");
	m.put("twqad", "s23as");
	m.put("zdcxd", "sd54s");
		
	Set<String> s1 = m.keySet();
	System.out.println("keySet遍历");
	for (Iterator iterator = s1.iterator(); iterator.hasNext();) {
		String str = (String) iterator.next();
		System.out.println(str + "=" + m.get(str));
		}
		
	Set<.Entry<String, String>> s2 = m.entrySet();
	System.out.println("entrySet遍历");
	for (Iterator iterator = s2.iterator(); iterator.hasNext();) {
		.Entry<String, String> entry =(.Entry<String, String>) iterator.next();
		System.out.println(entry.getKey() + "=" + entry.getValue());
	}
