it depends
mostly it is written in lower case
but few start with an uppercase
as Java is case sensitive
uppercase
You can use the toUpperCase() method on a String to convert any String to all uppercase.
System.out.println("text"); or System.out.print("text"); Please note that Java is case sensitive, meaning you must match uppercase and lowercase exactly.
You can find a list of Java keywords in the Wikipedia article "List of Java keywords". These keywords may not be used for variables or other user-defined names.
I'll just write a function to do that, I hope the good people won't try to run it as it is.... void function() { char c = 'a'; if( c >= 'a' && c <='z' ) System.out.println("LowerCase"); else if( c>='A' && c <='Z' ) System.out.println("UpperCase"); else System.out.println("Special Character"); }

As far as I know, keywords are part of the implementation of Java, and cannot be defined or redefined.
As of Java 1.5, there are 50 keywords defined, 48 of which are used (const and goto are unusable keywords).abstractcontinuefornewswitchassertdefaultgotopackagesynchronizedbooleandoifprivatethisbreakdoubleimplementsprotectedthrowbyteelseimportpublicthrowscaseenuminstanceofreturntransientcatchextendsintshorttrycharfinalinterfacestaticvoidclassfinallylongstrictfpvolatileconstfloatnativesuperwhile
CamelCase is a naming convention where the first word of a variable name starts with a lowercase letter, while each subsequent word begins with an uppercase letter. For example, a variable name in camelCase might look like myVariableName. This style enhances readability by visually distinguishing the start of new words within the variable name without using spaces or underscores. It is commonly used in programming languages such as JavaScript and Java.
To convert the string sSpoken Tutorial into uppercase in most programming languages, you can use a built-in function or method. For example, in Python, you would use sSpoken_Tutorial.upper(), while in Java, you would use sSpoken_Tutorial.toUpperCase(). Both of these methods will transform all lowercase letters in the string to uppercase.
True and false are literals(special built-in value) in java and cannot be used as keywords.
No. Keywords are not called or known as Metadata in Java
