Question

What is the output of the following Java program?

package test; import java.util.*; class Main { public static void main(String[] argh) { StringTokenizer st = new StringTokenizer("{5A=1500,2B=1950,5A=1000,3C=1770}", ("{=,}")); Map hm = new HashMap(); while (st.hasMoreTokens()) { hm.put(st.nextToken(), st.nextToken()); } System.out.println(hm.toString()); } }

Answer 1

The given java program is :

import java.util.*;​

class Main {

public static void main(String[] argh) {

StringTokenizer st = new StringTokenizer("{5A=1500,2B=1950,5A=1000,3C=1770}", ("{=,}"));

Map hm = new HashMap();

while (st.hasMoreTokens()) {

hm.put(st.nextToken(), st.nextToken());

}

System.out.println(hm.toString());

}

}

So, the output of the above java program is :

{2B=1950, 3C=1770, 5A=1000}
