求教 Object 转 Object[][]

[bog397404480]

public class test {
    public static void main(String[] args) {
         String [] colNames = null;
         Object[][] vals = null;

        Object data = "{\"张三\",\"13052300000\"}, {\"李四\",\"13052300001\"}, {\"王五\",\"13052300002\"}";

        colNames = new String[]{"姓名","电话"};

        vals = new Object[][]{ data };
    }
}

返回： Error: 不兼容的类型: java.lang.Object无法转换为java.lang.Object[][]

请教 怎么将 data 转为 vals

[new_bug1234]

可以用split方法将data分割开，然后转为数组类型。至于方法吗，可以查API.

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Test52 {

	public static void main(String[] args) {
		Object[][] vals = null;

		String data = "{\"张三\",\"13052300000\"}, {\"李四\",\"13052300001\"}, {\"王五\",\"13052300002\"}";

		vals = new Object[data.length() - data.replaceAll("\\{", "").length()][2];

		Pattern pattern = Pattern.compile("(?<=\\{)(.+?)(?=\\})");
		Matcher m = pattern.matcher(data);

		int i = 0;
		while (m.find()) {
			vals[i][0] = m.group().split(",")[0];
			vals[i][1] = m.group().split(",")[1];
			i++;
		}
		System.out.println(data);
	}
}
