What is the correct way to convert a string to uppercase in Java?Question 1Answera.toUpper()b.toUpperCase()c.uppercase()d.convertToUpperCase()
Solution
The correct way to convert a string to uppercase in Java is by using the method toUpperCase(). So, the answer is b.toUpperCase().
Here is a step by step guide on how to do it:
- First, you need to have a string. Let's say we have a string called "myString". You can declare it like this:
String myString = "Hello, World!";
- Next, you can use the method toUpperCase() to convert all the letters in "myString" to uppercase. Here is how you can do it:
myString = myString.toUpperCase();
- Now, if you print "myString", you will see that all the letters are in uppercase:
System.out.println(myString);
This will output: "HELLO, WORLD!".
So, the correct answer to your question is b.toUpperCase().
