Problem using StringTokenizer

[Ankur Premi]

I am trying to use StringTokenizer for saving the value of val (See code below) in different variables.

I have written this code. But this code is returning null values. It's not saving the value of val corresponding to the key.

  import java.util.StringTokenizer;
class add {
static String in = "name=john;age=20;sex=male";
public static void main(String args[]) {
StringTokenizer st = new StringTokenizer(in, "=;");
while(st.hasMoreTokens()) {

    String key = st.nextToken();
    String val = st.nextToken();

if(key=="name"){
    String s1=val;
}


if(key=="age"){
    System.out.println(key + "\\t" + val);
String s2=val;
}


if(key=="sex"){
    System.out.println(key + "\\t" + val);
String s3=val;
}

}
}
}
  

Please help me.

I suppose, it wont even enter the three if statements. How did you decide it gives null values?
Use equals() to compare the contents of 2 strings.'==' is used to check reference equality.

Why? It is a legacy class.
