Step 1
Given the following Java statement:
String s1 = "Java is cool!";
Answer the following questions:
a) What is the length of the string s1?
b) What is the character at index 6 of the string s1?
c) What is the index of the first occurrence of the character "J" in the string s1?
d) What is the substring of the string s1 that starts at index 8 and ends at index 11?
Task:
Write a Java program that declares the string s1 and uses the length(), charAt(), indexOf(), and substring() methods to obtain the answers to the above questions. Print the results of each method call to the console.
