    Default How to Accumulate results

    Hello I am very new to java and am writing a method that shifts each letter in a String over in the alphabet n times. I am having trouble figuring out a way to accumulate the results
    Code:
    public String shift(int n){
     
    char character; 
     
    for (int i = 0; i < text.length(); i++)
    {
    character = text.charAt(i); 
    if(character>='A'&& character<='Z'){
    character = (char) (character + n);
    if (character>'Z') 
    character-=26;
     
    // How to accumulate?
    text=Character.toString(character);
     
    }
     
    } 
    return text; 
    }

    any advice is appreciated! I have been suggested a String builder, but im not quite sure on how to use it, is there a simpler method?

    Didn't even have the courtesy to thank the member who made the suggestion.
