Question

Lab 6                                   

Given the String

String str = “Zhrx.aghkio.Gko123”;

(a) Write Java code using the String class methods indexOf and substring to extract the three string surrounded by the periods. In other words

1. String s1 will contain Zhrx,
2. String s2 will contain aghkio and
3. String s3 will contain Gko123.

(b) Write a method of the form

public static String minStr(String str1, String str2)

which returns the string which is “smaller” based on the decimal values of the characters in the string. Thus, Zaa would be “smaller” than bxy because the character Z has a lower decimal values than b. Use the String method compareTo as part of your code.

(c) In main, print the value returned by

        minStr(minStr(s1,s2),s3)

Answer 1

package com.abc;

public class StringDemo {

   public static void main(String[] args) {
       String str = "Zhrx.aghkio.Gko123";
       String s1=str.substring(0,4);
       String s2=str.substring(5,11);
       String s3=str.substring(12,str.length());
       System.out.println(s1);
       System.out.println(s2);
       System.out.println(s3);
       String finalvalue=StringDemo.minStr(s1, s2);
       String finalvalue1=StringDemo.minStr(finalvalue, s3);
       System.out.println(finalvalue);
       System.out.println(finalvalue1);
   }
   public static String minStr(String str1, String str2) {
      

   int var1 = str1.compareTo( str2 );
   System.out.println("str1 & str2 comparison: "+var1);
   return str2;
   }

}
