java please please help

Dear Friends plz help me to complete this program
import java.util.*;
public class StringDemo {
static String a="{a=100;b=200;c=300}";
public static void main(String args[])
{
String b[]=a.split(";");
for(int i=0;i {
System.out.println(b[i]);
}
}

here i have to split this whole String "a" into broken tokens like a=100,b=200,c=300 so have used split method and now have to seperate the key and values like key:a and value:100.But should not use StringTokenizer but can use any other collection like HashMap,HashTable....etc.I dont know how to add this string array here b[] to HashMap so that i can seperate key and value using Map.Entry.Please help me!

import java.util.*; 

public class StringDemo {
    static String a="{a=100;b=200;c=300}"; 
    public static void main(String args[]) {
        String st=a.replace("{","");
        String s=st.replace("}","");

        String[] b = s.split(";");

    String[][] str = new String[b.length][]; 
    int r = 0;
    for (String row : b) {
        str[r++] = row.split("\\=");
    }
    Map<String, String> map = new HashMap<String, String>(str.length);
    for (String[] array : str){
    map.put(array[0], array[1]);
    }
    Set set = map.entrySet();
    Iterator it = set.iterator();
while(it.hasNext()) {
Map.Entry me = (Map.Entry)it.next();
System.out.println(me.getKey() + ": "+me.getValue());
} 
}
}
