//It will check address of giver reference variable &return boolean value

//It will give the length of string
System.out.println(s.length());

//It will return the character of 4th index
System.out.println(s.charAt(4));

//To remove whitespaces from starting and ending of perticular string
System.out.println(s.trim());

//to check string is empty or not it will return boolean value
System.out.println(s.isEmpty());

// It will replace character 'e' with 's'
System.out.println(s.replace("e", "S"));

//return the address of the string object
System.out.println(s.hashCode());

//Convert the given string into upperCase
System.out.println(s.toUpperCase());

// split() will convert string into string array

Add code for some real time interview questions like how to get number of Captial A in the string, “I Am Awesome”. Write code to make use of these methods, mere knowning these methods is not enough, you need to learn to make use of it in real logical problems. Add solutions to top 5 string manipulation questions here.
