String river = "This is a Test"; to be lowercase using Eclipse.exe

Question

How can I get String river = "This is a Test"; to become lowercase using Eclipse? I have already tried multiple ways using bigRiver but it doesn't work.

Have you tried river.toLowercase()? or better yet river.toLowercase(Locale.English);

String is immutable in Java, so you must assign the reference for the river to be modified.

String river = "This is a Test";
System.out.printf("Before: %s%n", river);
river = river.toLowerCase(Locale.ENGLISH);
System.out.printf("After: %s%n", river);

Outputs

Before: This is a Test
After: this is a test
