StringBuilder(Int32): 

  Creates a new instance of the StringBuilder class using the specified capacity

Pass a string value as an argument: For example, ` StringBuilder s = new StringBuilder(`GeeksforGeeks'');

Stringbuilder in Java: Constructors, Methods, and Examples ...

StringBuilder in Java is a class used to create a mutable, or in other words, a modifiable succession of characters. Like StringBuffer, the StringBuilder class is an alternative to the Java Strings Class, as the Strings class provides an immutable succession of characters

Example:

// C# program to demonstrate the 

// StringBuilder.Append(value) and 

// StringBuilder.AppendLine(value) method 

using System; 

using System.Text; 

class GFG { 

// Main Method 

public static void Main() 

{ 

// "20" is capacity 

StringBuilder s = new StringBuilder("HELLO ", 20); 

s.Append("GFG"); 

// after printing "GEEKS" 

// a new line append 

s.AppendLine("GEEKS"); 

s.Append("GeeksForGeeks"); 

Console.WriteLine(s); 

} 

}
