Java String Exercises: Read a string and if one or both of the first two characters is 'x', return without those 'x', 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 'x', return without those 'x',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

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) != 'o')
      temp += stng.charAt(i);
    else if (i == 1 && stng.charAt(i) != 'o')
      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 =  "ooboat";
      System.out.println("The given strings is: "+str1);
      System.out.println("The new string is: "+m.exceptTwoO(str1));
	  }
}

Sample Output:

The given strings is: ooboat
The new string is: boat

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