teststring1.java

正则表达式的一个小例子

public class TestString1 {
	private String str;
	private int dig;
	private int low;
	private int up;
	private int others;
	public TestString1(String s)
	{
		str=s;
		for(int i=0;i<str.length();i++){
			
			char c=str.charAt(i);
			
			if(c>='0'&&c<='9') dig++;
			else if(c>='a'&&c<='z') low++;
			else if(c>='A'&&c<='Z') up++;
			else  others++;
		}
	}

	public String getStr() {
		return str;
	}

	
	public int getDig() {
		return dig;
	}

	public int getLow() {
		return low;
	}

	public int getUp() {
		return up;
	}
	public int getOthers() {
		return others;
	}
	
	public static void main(String[] args) {
		
		TestString1 s=new TestString1("r78@#F.?fewf.  fe3fw0f");
		
		System.out.println("字符串:"+s.getStr());
		System.out.println("有数字:"+s.getDig());
		System.out.println("有小写字母:"+s.getLow());
		System.out.println("有大写字母:"+s.getUp());
		System.out.println("其他类型:"+s.getOthers());
