Question

Write a program that uses String method regionMatches to compare two strings input by the user. The program should prompt the user to enter two strings, the starting index in the first string, the starting index in the second string, and the number of characters to be compared. The program should print whether or not the strings are equal, (Ignore the case of the characters during comparison.) 四SAMPLE RUN #1: java StringCompare Highlight: None D Show Highlighted Only Interactive Session Hide Invisibles Enter first string :Have yourself-a merry.little christmas.

Answer 1

import java.util.Scanner;

public class Compare {

/**

* @param args

*/

public static void main(String[] args) {

//takinng input from the user

Scanner sc=new Scanner(System.in);

System.out.print("Enter first string\t:");

String input1=sc.nextLine();

System.out.print("Enter second string\t:");

String input2=sc.nextLine();

System.out.print("Enter start index for first string\t:");

int str1startindex=sc.nextInt();

System.out.print("Enter start index for second string\t:");

int str2startindex=sc.nextInt();

System.out.print("Enter no of characters to be compared\t:");

int charCount=sc.nextInt();

//here true means igore case

//str1startindex means start index of the string 1 to compare

//input2 means second string

//str2startindex means start index of the string 2 to compare

//charcount means no of characters to compare in both string

//it will return true if both places are equal otherwise return false

boolean match = input1.regionMatches(true,str1startindex, input2, str2startindex, charCount);

System.out.println(match);

}
