What are all the ways to append a string in java?

Question

To append a string in java this is the method I use StringBuilder append() Is there another way to do this? Here is an example of the StringBuilder append(). If there is another can someone explain in detail how you would do it. This method is taking to much time to code.

// Java program to illustrate the 
// StringBuilder append(boolean a) 
import java.lang.*; 
  
public class Geeks { 
  
    public static void main(String[] args) 
    { 
  
        StringBuilder sb1 = new 
                      StringBuilder("Welcome to Geeksforgeeks "); 
        System.out.println("Input: " + sb1); 
  
        // Appending the boolean value 
        sb1.append(true); 
        System.out.println("Output: " + sb1); 
  
        System.out.println(); 
  
        StringBuilder sb2 = new StringBuilder("We fail- "); 
        System.out.println("Input: " + sb2); 
  
        // Appending the boolean value 
        sb2.append(false); 
        System.out.println("Output: " + sb2); 
    } 
}
