We will use the online Java editor to write a simple Java program.

public class SplitLine {public static void main(String []args) {String line = "I love Java programming very much";String[] words = line.split(" ");System.out.println("There are " + words.length + " words.");	}
}

Run the program and the result is as folllows:

There are 6 words.

describe - description

We cannot describe her beauty with proper words.
Her beauty defies any description.

1. Just now I created a Java class named SplitLine.
2. In the class there is a main method as the entrance of the program, which means the program cannot be executed without a main method.
3. The first statement defines a String variable named line, and assigns a String constant to the variable. This work can be called the variable initialization.
4. In the second satement, we call the split method of the variable line, pay attention that the method needs a space as the parameter, and then assign the result to the String array named words.
