Program Java za uporabo velikih črk vsake besede v nizu

V tem primeru se bomo naučili pretvoriti prvo črko niza v veliko črko v Javi.

Če želite razumeti ta primer, morate poznati naslednje programske teme Java:

Java Java
Niz Java vUpperCase ()

Primer 1: Program Java za izdelavo prve črke velikega niza

 class Main ( public static void main(String() args) ( // create a string String name = "programiz"; // create two substrings from name // first substring contains first letter of name // second substring contains remaining letters String firstLetter = name.substring(0, 1); String remainingLetters = name.substring(1, name.length()); // change the first letter to uppercase firstLetter = firstLetter.toUpperCase(); // join the two substrings name = firstLetter + remainingLetters; System.out.println("Name: " + name); ) )

Izhod

 Ime: Programiz

V primeru smo pretvorili prvo črko imena niza v velike črke.

Primer 2: Pretvorite vsako besedo niza v veliko črko

 class Main ( public static void main(String() args) ( // create a string String message = "everyone loves java"; // stores each characters to a char array char() charArray = message.toCharArray(); boolean foundSpace = true; for(int i = 0; i < charArray.length; i++) ( // if the array element is a letter if(Character.isLetter(charArray(i))) ( // check space is present before the letter if(foundSpace) ( // change the letter into uppercase charArray(i) = Character.toUpperCase(charArray(i)); foundSpace = false; ) ) else ( // if the new character is not character foundSpace = true; ) ) // convert the char array to the string message = String.valueOf(charArray); System.out.println("Message: " + message); ) )

Izhod
