请求分拆的算法

[lovezx1028]

Name Emial
a gmail,163
b 126,163

分拆之后的结果是：
id name Emil
1 a gmail
2 a 163
3 b 126
4 b 163
java算法。

for example

class EmailInfo {
    String name;
    String email;
    public EmailInfo(String name, String email) {
        this.name = name;
        this.email = email;
    }

    public String getName() {returne this.name;}
    public String getEmail() {return this.email;}

    public String toString() {
        return String.format("name=[%s],email=[%s]", name, email);
    }
}

public class NewEmailInfo extends EmailInfo {
    int id,
    public NewEmailInfo(int id, String name, String email) {
        super(name, email);
        this.id = id;
    }

    public getId () {return this.id;}
 
    public String toString() {
        return String.format("id=[%d],name=[%s],email=[%s]", id, name, email);
    }

    public static void main(String[] args) {
        EmailInfo[] ei = new EmailInfo[]{new EmailInfo("a", "gmail,163"),
                                         new EmailInfo("b", "126,163")};
        System.out.println("----------before----------");
        for (EmailInfo e : ei) {
            System.out.println(e);
        }

        NewEmailInfo[] nei = new NewEmailInfo[ei.length];
        int id = 0, i = 0;
        for (EmailInfo e : ei) {
            for (String email : e.getEmail().split(",")) {
                nei[i++] = new NewEmailInfo(++id, e.getName(), email);
            }            
        }

        System.out.println("----------after----------");
        for (NewEmailInfo e : nei) {
            System.out.println(e);
        }
    }
}

你自己封装下吧。

public class Test8 {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		String[] src ={"a gmail,163","b 126,163"};
		
		int num = 1;
		StringBuffer sb = new StringBuffer();
		for (int i = 0; i < src.length; i++) {
			String[] s = src[i].split(" |,");
			for(int j=1;j<s.length;j++)
			{
				sb.append(num+++"\t");
				sb.append(s[0]+"\t");
				sb.append(s[j]+"\t");
				sb.append("\n");
			}
		}
		System.out.println(sb.toString());
	}

}
