Solution
Here is the Java code that fulfills your requirements:
public class HelloWorld {
public static void main(String[] args) {
// Declare a String object s, assigned with the literal String "Hello World!"
String s = "Hello World!";
// Print the String object s as formatted output
System.out.println(s);
// Declare the integer-typed variable len, and use the .length() String method on s to assign it's value
int len = s.length();
// Print the variable len as formatted output
System.out.println(len);
// Declare the char-typed variable ch and use the .charAt(6) String method on s to assign it's value
char ch = s.charAt(6);
// Print the variable ch as formatted output
System.out.println(ch);
}
}
This code will output:
Hello World!
12
W
The first line of output is the string "Hello World!". The second line is the length of the string, which is 12. The third line is the character at the 6th index of the string, which is 'W'.
