Java String Exercises: Check whether the character immediately before and after a specified character is same in a given string
Java String: Exercise-80 with Solution
Write a Java program to check whether the character immediately before and after a specified character is same in a given string.
Sample Solution:
Java Code:
import java.util.*;
public class Main
{
public boolean leftAndRightSame(String stng)
{
int l = stng.length();
boolean found = true;
for (int i = 0; i < l; i++)
{
String tmpString = stng.substring(i,i+1);
if (tmpString.equals("#") && i > 0 && i < l-1)
{
if (stng.charAt(i-1) == stng.charAt(i+1))
found = true;
else
found = false;
}
}
return found;
}
public static void main (String[] args)
{
Main m= new Main();
String str1 = "moon#night";
System.out.println("The given string is: "+str1);
System.out.println("The before and after character are same: "+m.leftAndRightSame(str1));
}
}
Sample Output:
The given string is: moon#night The before and after character are same: true The given string is: bat##ball The before and after character are same: false The given string is: #moon#night The before and after character are same: true
