TRUE
Here is how a java program works. A java program written as . java file is is first compiled to intermediate code called byte code. This byte code can be executed in any platform. The byte code is then executed in Java Virtual Machine by interpreting. This byte code can be executed in any JVM. So the answer is TRUE
Add Answer to:

true or false in JAVA 1) A literal value is a value that is typed directly into the code, such as 10, 14.6, or "Bob". 2) Local variables can only be accessed from within the block in which they are defined. 3) All variables must be declared before they can be used. 4) If a method returns nothing, its return type should be null. 5) A method with an int parameter can be invoked with a String argument. 6) A...

Write a program that reads a Java source-code file and reports the number of keywords (including null, true, and false) in the file. If a keyword is in a comment or in a string, don’t count it. Test your program to count the keywords in the Welcome.java file: Please input the Java filename: Welcome.java The number of keywords in the program is 6

How can you identify which file is the java source code? What can you do with java byte code? What can you do with java source code? Be able to know the difference between a statement, an expression and a literal. What is the value of a literal (as in, what is the literal that represents the int zero)? What is the value of a literal (as in, what is the literal that represents the capital letter A)? What is...
