Java String Exercises: Check whether a substring appears before a period(.) within a given string
Java String: Exercise-73 with Solution
Write a Java program to check whether a substring appears before a period(.) within a given string.
Sample Solution:
Java Code:
import java.util.*;
public class Main
{
public Boolean abcBeforePeriod(String stng)
{
int len = stng.length();
String abc = "abc";
Boolean match = false;
if (len < 3)
return false;
for (int i = 0; i < len - 2; i ++)
{
String temp = stng.substring(i, i+3);
if (temp.compareTo(abc) == 0 && i == 0)
match = true;
else if(temp.compareTo(abc) == 0 && stng.charAt(i-1) != 46)
match = true;
}
return match;
}
public static void main (String[] args)
{
Main m= new Main();
String str1 = "testabc.test";
System.out.println("The given string is: "+str1);
System.out.println("Is 'abc' appear before period? "+m.abcBeforePeriod(str1));
}
}
Sample Output:
The given strings is: testabc.test Is 'abc' appear before period? true The given string is: test.abctest Is 'abc' appear before period? false
