Java String Exercises: Read a string and if one or both of the first two characters is equal to specified character return without those characters otherwise return the string unchanged

Java String: Exercise-67 with Solution

Write a Java program to read a string and if one or both of the first two characters is equal to specified character return without those characters otherwise return the string unchanged.

Sample Solution:

Java Code:

import java.util.*;
public class Main
{
public String exceptTwoO(String stng) 
{
  String temp = "";
  for (int i = 0; i < stng.length(); i++) 
  {
    if (i == 0 && stng.charAt(i) != 'x')
      temp += stng.charAt(i);
    else if (i == 1 && stng.charAt(i) != 'x')
      temp += stng.charAt(i);
    else if (i > 1)
      temp += stng.charAt(i);
  }
  return temp;
}
public static void main (String[] args)
    {
      Main m= new Main();
      String str1 =  "xxcyte";
      System.out.println("The given strings is: "+str1);
      System.out.println("The new string is: "+m.exceptTwoO(str1));
	  }
}

Sample Output:

The given strings is: xxcyte
The new string is: cyte

Previous: Write a Java program to read a string and return the string without the first two characters. Keep the first character if it is 'g' and keep the second character if it is 'h'.
Next: Write a Java program to read a string and returns after removing a specified character and its immediate left and right characters.

Directory Content:

Java allows you to get the names of all subdirectories and files in a folder as an array, which can then be sequentially viewed.

import java.io.*;
  
public class ListContents {
  public static void main(String[] args) {
    File file = new File("//home//user//Documents/");
    String[] files = file.list();
  
    System.out.println("Listing contents of " + file.getPath());
    for(int i=0 ; i < files.length ; i++)
    {
      System.out.println(files[i]);
    }
  }
}
