String Methods:
String class contains several methods, which are used to perform string manipulations.
Some examples of string methods used for manipulating strings are:
- “equals(s1)” - Returns true if the given string is equals to string “s1”.
- “compareTo(s1)” - Returns an integer greater than “0” if the string is greater, returns “0” if both the strings are equals and returns less than “0” if the given string less than s1.
- “contains(s1)” -Returns true if “s1” is a substring of the given string.
- “indexof(ch)” - Returns the index of the first occurrence of character “ch” in the string. Else, it will return -1 if not matched.
- “lastIndexof(ch)” - Returns the index of the last occurrence of character “ch” in the string. Else, it will return -1 if not matched.
- “length()” - Returns the number of characters that the string contains .
- “charAt(index)” - Returns the character from the string at the specified index.
- “toUpperCase()” - Returns a new string contains uppercase letters.
- “toLowerCase()” - Returns a new string contains lower letters.
