Hi@akhtar,

You can use the StringBuffer class. It provides a method deleteChartAt(). The method deletes a character from the specified position. We use the method to remove a character from a string Java. It accepts a parameter index of type int. The index is the position of a character we want to delete.

public class RemoveLastCharcter1  
{  
public static void main(String args[])  
{  
String string = "I am learning Java Concepts";  
//creating a constructor of StringBuffer class  
StringBuffer sb= new StringBuffer(string);  
//invoking the method  
sb.deleteCharAt(sb.length()-1);  
//prints the string after deleting the character   
System.out.println(sb);  
}  
}
