Explanation / Answer
Class RemoveChr{
List<Character> char= new ArrayList<>();
char.add('a');
char.add('p');
char.add('e');
char.add('x');
char.remove(Character.valueOf('p'));//to remove specified character
// to remove a character based on particular index/position
String st="apex";
StringBuilder builder = new StringBuilder(st);
//to remove 2nd character from the array list
builder.deleteCharAt(1);//since index starts at 0
system.out.println("enter the charater to be deleted:");
System.out.println("input string:"+st);
system.out.println("string after removing character :"+builder.toString);
}
output:
enter the charater to be deleted: p
input string: apex
string after removing character:aex
