In this example, we shall show you how to convert a String toLowerCase in Java. The String class represents character strings. All string literals in Java programs, such as "abc", are implemented as instances of this class.
1. Java Convert String toLowerCase
To convert a String toLowerCase in Java, one should perform the following steps:
- Create a new String
- Use
toLowerCase()API method of String. This method converts all of the characters in this String to lower case using the rules of the default locale. This is equivalent to callingtoLowerCase(Locale.getDefault())
Note that in case you’d like to do the opposite, there is the toUpperCase method. The toUpperCase method works exactly like the toLowerCase, but converts the string to only contain capital letters instead of lower case.
In the code snippet below you can see an example of the conversion:
public class ConvertStringToLowerCase {
public static void main(String[] args) {
String s = "Java Code Geeks";
System.out.println("Original String: " + s);
String su = s.toLowerCase();
System.out.println("String to lower case: " + su);
}
}Output
Original String: Java Code Geeks
String to lower case: java code geeks
Here we just create a String s, then we print it. Afterwards, we create a new string and we assign the value that is returned from toLowerCase method when called by the previously created string. In the end, we print the result of the “su” string. The result is the same string but all the letters are in lower case, exactly what we expected
