Java String Exercises: Remove a specified character from a given string

Java String: Exercise-103 with Solution

Write a Java program to remove a specified character from a given string.

Sample Solution:

Java Code:

public class Main {    
    public static void main(String[] args) {
       String str1 = "abcdefabcdeabcdaaa";
       char g_char = 'a';
        String result = remove_Character(str1, g_char);
        System.out.println("\nOriginal string:");
        System.out.println(str1);    
        System.out.println("\nSecond string:");
       System.out.println(result);                                
   }
  public static String remove_Character(String str1, char g_char) {
       if (str1 == null || str1.isEmpty()) {
          return "";
       }
       StringBuilder sb = new StringBuilder();
       char[] chArray = str1.toCharArray();
       for (int i = 0; i < chArray.length; i++) {
           if (chArray[i] != g_char) {
               sb.append(chArray[i]);
           }
       }
       return sb.toString();
   }
}

Sample Output:

Original string:
abcdefabcdeabcdaaa

Second string:
bcdefbcdebcd
