Java string remove character

String str = "abcdDCBA123";
String strNew = str.replace("a", ""); // strNew is 'bcdDCBA123'

# subString(int start, int end);

String a = "Hello!";
b = a.subString(0,a.length()-1) #Remove the last String
# b should be "Hello" then

public extractLetters(String str){
	String result="";
	for(int i= 0; i< str.length; i++){
	    if(Character.isLetter(str.charAt(i))){
	    result+=str.charAt(i);
	  	}
	}

public class RemoveParticularCharacter
{
   public static void main(String[] args)
   {
      String strInput = "Hello world java";
      System.out.println(removeCharacter(strInput, 6));
   }
   public static String removeCharacter(String strRemove, int r)
   {
      return strRemove.substring(0, r) + strRemove.substring(r + 1);
   }
}

System.out.println(
    "a\u0000b\u0007c\u008fd".replaceAll("\\p{Cc}", "")
); // abcd

// Works only if you have a certain character at which you want to cut
String text = "Image.png";

String[] cutText = text.split("\\.");

// cutText[0] has value "Image"
// cutText[1] has value "png"
