   public static void main( String args[] ) {
       boolean a;
      TimeZone tz = TimeZone.getDefault();
      TimeZone tz1 = TimeZone.getDefault();

transitions=3,lastRule=null]

Example 3

import java.util.*;
public class TimeZoneHasSameRulesExample3{
   public static void main( String args[] ) {
       boolean a;
      TimeZone tz = TimeZone.getTimeZone("Indian/Mahe");
      TimeZone tz1 = TimeZone.getTimeZone("Indian/Mahe");
      a = tz.hasSameRules(tz1);
      System.out.println("Comparison result:" +a );
      System.out.println("TimeZone1 of Indian/Mahe :" + tz);
      System.out.println("TimeZone2 of Indian/Mahe:" + tz);
      
   }    
}

Output:

Comparison result: true
TimeZone1 of Indian/Mahe :sun.util.calendar.ZoneInfo[id="Indian/Mahe",offset=14400000,dstSavings=0,useDaylight=false,
transitions=3,lastRule=null]
TimeZone2 of Indian/Mahe:sun.util.calendar.ZoneInfo[id="Indian/Mahe",offset=14400000,dstSavings=0,useDaylight=false,
transitions=3,lastRule=null]
