how add strings together
//Java
String firstName = "BarackObama";
String lastName = " Care";
//First way
System.out.println(firstName + lastName);
//Second way
String name = firstName + lastName;
System.out.println(name);
//Third way
System.out.println("BarackObama" + " Care");Concatenating Strings
//The String class includes a method for concatenating two strings :
string1.concat(string2);
This returns a new string that is string1 with string2 added to it at the end. You can also use the concat() method with string literals
"My Name is".concat("Zara");
Strings are most commonly concatenated with the "+" operator
"Hello," + " world" + "!"
Example
public class StringDemo {
public static void main(String args[]) {
String string1 = "saw I was ";
System.out.println("Dot " + string1 + "Tod");
}

char charAt(int index) - Returns the character at the specified index.
int compareTo(Object o) - Compares this String to another Object.
String concat(String str) - Concatenates the specified string to the end of this string.
