The șir java toLowerCase() metoda returnează șirul cu litere mici. Cu alte cuvinte, convertește toate caracterele șirului în litere mici.

Metoda toLowerCase() funcționează la fel ca metoda toLowerCase(Locale.getDefault()). Utilizează în interior localitatea implicită.

Java String toLowerCase(Locale locale) Metoda Exemplu 2

Această metodă ne permite să trecem și locale pentru diferitele limbi. Să vedem mai jos un exemplu în care primim șir în engleză și turcă ambele.

 import java.util.Locale; public class StringLowerExample2 { public static void main(String[] args) { String s = &apos;JAVATPOINT HELLO stRIng&apos;; String eng = s.toLowerCase(Locale.ENGLISH); System.out.println(eng); String turkish = s.toLowerCase(Locale.forLanguageTag(&apos;tr&apos;)); // It shows i without dot System.out.println(turkish); } }

Ieșire:

 javatpoint hello string javatpo?nt hello str?ng
