The computer does not understand the characters internally, it stores manipulated characters as the combination of the 0's and 1's. Python string is the collection of the characters surrounded by single quotes, double quotes, or triple quotes. But, before learning those methods, let us have a brief introduction to strings in python. Hence, it is chaotic to pay attention to every string you create and use while programming, and also quite difficult to correct it manually.Īs it is important and default format to capitalize the first letter of every word for readers convenience, we have presented a detailed article representing 8 different methods to capitalize the first letter in python and the examples. While programming in python, some strings are used in uppercase while some are in lowercase and some in combination. are one of the most used python data structures. String result = firstinLower+middle+lastinUpper combine everything and get the final string get middle parts of the word, except first and last character String firstinLower = first.toLowerCase() get first character and convert it to lower case String last = str.substring(size-1,size) get last character and convert it to upper case In this approach, we will make use of Algorithm-1 import Approach-1: By Using Inbuilt substring Method Example Let’s see the program along with its output one by one. We have provided the solution in different approaches. Step 4 − Then combine first, middle and last value and get the final string/word. Step 3 − Get the middle characters (except first and last character) with the help of charAt() method and a for loop. Then convert it to lower and upper case by using toLowerCase() method and toUpperCase() method respectively. Step 2 − Get the first and last letter by using charAt() method. Step 4 − Combine first, middle and last value and get the final string/word. Step 3 − Get the middle characters (except first and last character) with the help of substring() method. Step 2 − Get the first and last letter by using the substring() method. Step 1 − Get the string/word either by initialization or by user input. Also we have used only inbuilt methods of String Class. But here we have tried to solve the problem without using the array concept. Note − This problem can be solved with the Array concept also. Syntaxīelow is the syntax for that − String.valueOf(Object obj) To convert different types of values to String value Java String class provides valueOf() method. Where, index refers to the index of the character that you need. Syntaxīelow is the syntax for that − str.charAt(int index) To get a character at a specified index Java String class provides the charAt() method. Where, startIndex is inclusive and endIndex is exclusive. Str.substring(int startIndex, int endIndex) Syntaxīelow is the syntax for that − str.substring(int startIndex) To get a substring of the original string Java String class provides a substring() method. To get the length of the String Java String class provides a length() method.īelow is the syntax for that − str.length() Suppose the input string is “Programming”Īfter converting the first letter to lower and last letter to capital, the new string will be “programminG” Syntax To Show You Some Instances Instance-1Īfter converting the first letter to lower and last letter to capital, the new string will be “hellO” Instance-2Īfter converting the first letter to lower and last letter to capital, the new string will be “javA” Instance-3 In this article we will see how the first and last letter can be converted into lower and upper case respectively. We have to convert the first letter of the word to lowercase and last letter of the word to uppercase. We have a String class provided by Java for creating and manipulating strings. In Java, Strings are considered as objects. String is a sequence of character values.
