Difference between String[] (with square brackets) and String (without square brackets) in Java

Question

Just starting to learn Java, I found that "String" in this function has two square brackets beside:

public static void main (String[] parameter){
    System.out.println("hello world");
}

But this one has not:

public void setName(String name){
    this.name = name;
}

What is the diference?

He's asking exactly the same thing as you. "what do the square brackets mean? in Java". Use Google before StackOverflow. — Erwin Bolwidt, Apr 22 '16 at 03:04

[] signifies an array, or a list of many Strings, whilst String is just one String.
