D.55

30

D.syntax

When the compiler is compiling your code (i.e., converting your code into instructions the machine understands), it will report problems that it finds in your code.

31
A.Text

import java.text.DecimalFormat;

32
A. Assembly language

A low-level programming language is a programming language that provides little or no abstraction from a computer's instruction set architecture—commands or functions in the language map closely to processor instructions. Generally this refers to either machine code or assembly language.

33. Encapsulation

A language construct that facilitates the bundling of data with the methods (or other functions) operating on that data

34. Both within the range of acceptable values and of the same data type as acceptable values.

In computer programming, a sentinel value (also referred to as a flag value, trip value, rogue value, signal value, or dummy data) is a special value in the context of an algorithm which uses its presence as a condition of termination, typically in a loop or recursive algorithm.

35. bytecode

The Java compiler translates Java programs into a language called Java bytecode.Although bytecode is similar to machine language, it is not the machine language of any actual computer. A Java interpreter is used to run the compiled Java bytecode program. (Each type of computer needs its own Java bytecode interpreter, but all these interpreters interpret the same bytecode language.)

36. Set braces { }   // check below example everything starts with braces

if(Boolean_expression) {
   // Executes when the Boolean expression is true
}else {
   // Executes when the Boolean expression is false
}

class GFG {

    // Driver Code
    public static void main(String args[])
    {
}

while(Boolean_expression) {
   // Statements
}

for(initialization; Boolean_expression; update) {
   // Statements
}

do {
   // Statements
}while(Boolean_expression);

if you got your answers satisfaction then please appreciate my post with thumbs up , Thanks a lot .... :)
