How do I empty or clean the String Builder?

You are using StringBuilder in the loop and want to start with an empty StringBuilder and empty after x iterations.The functionality corresponding to the NET String Builder is not displayed. Only removal techniques appear to be too difficult in the document.

So how do we organize StringBuilder in Java?

Is the question correct to ask how to initialize StringBuilder in Java? I don't know the purpose because we're suddenly talking about four or four.

In Java, you can create a new StringBuilder instance and assign it to a variable or write delete().

StringBuilder builder = new StringBuilder();
builder.append("abc").append("def");
assertEquals(6, builder.length());

builder.delete(0, builder.length());
assertEquals(0, builder.length());
