It's been a little while since I've learned Java, but the exclamation point used to denote factorials (!) is already used in Java to denote a negation (e.g. a != 2 means a is not equal to 2). To create a factorial in Java, construct a for loop and multiply all the consecutive integers.

General syntax in creating a method?
A Java method declaration will look like this:[access modifier] [static] [final] [synchronized] [return type] [method name]([parameters])Where:access modifier is exactly one of the followingpublicprotected(no text)privatestatic, final, and synchronized are all optional.return type is exactly one of the followingvoidThe name of a Java primitiveThe name of a Java classmethod name is a valid Java identifier which must conform to all of the following rulesStarts with a lowercase letter (a-z), an uppercase letter (A-Z), a dollar sign ($), or an underscore (_)After the first character, may be a digit(0-9), a lowercase letter (a-z), an uppercase letter (A-Z), a dollar sign ($), or an underscore (_)May not be one of the Java keywordsMay not be one of the Java literals: true, false, or nullparameters is a comma-separated list of [type] [identifier] pairs, where:type is a valid Java primitive or class nameidentifier is a Java identifier, which conforms to the same rules as method name
Is unsigned int var valid in java?
No. Java uses no unsigned numbers.
Programming to calculate a factorial number?
double factorial(double N){double total = 1;while (N > 1){total *= N;N--;}return total; // We are returning the value in variable title total//return factorial;}int main(){double myNumber = 0;cout > myNumber;cout
Explain the term identifier in java?
Identifiers are the strings you use in Java source code to identify unique things, such as variables, classes, and methods. Identifiers may be any word beginning with a letter or underscore, and continuing with letters, numbers, and underscores. Identifiers are case sensitive.
Write a program in java for factorial?
// Iterative solution public static final long iterativeFactorial(final long n) { long factorial = 1; for (long i = 1; i <= n; i++) { factorial *= i; } return factorial; } // Recursive solution public static final long recursiveFactorial(final long n) { if (n <= 1) { return n; } return n * recursiveFactorial(n - 1); } // Arbitrary length solution - may take a while, but works on any positive number. public static final BigInteger factorial(final BigInteger n) { BigInteger factorial = BigInteger.ONE; for (BigInteger i = BigInteger.ONE; i.compareTo(n) <= 0; i = i.add(BigInteger.ONE)) { factorial = factorial.multiply(i); } return factorial; }
What is a factorial loop?
An example in Java, to compute 10!: int factorial = 1; for(int i = 1; i < 11; i++) { factorial *= i; }
What is the rules to be valid identifier?
In what language?
Is A N D is an identifier?
A N D is not an identifier as it has spaces in between each letter. A valid identifier DOES NOT have space in it.

Yacc program to recognize a valid variable which starts with letters followed by any number of level of digits?
%{ #include<stdio.h> int valid=1; %} %token digit letter %% start : letter s s : letter s | digit s | ; %% int yyerror() { printf("\nIts not a identifier!\n"); valid=0; return 0; } int main() { printf("\nEnter a name to tested for identifier "); yyparse(); if(valid) { printf("\nIt is a identifier!\n"); } }

What is the similarity between an identifier and a variable?
Answer:- identifier is the name like a, b, c, .... which is used to reference a memory location in a program. +-variable is the actual memory location which can hold values.so 'a' is an identifier to a variable which is memory location located somewhere in memory.Answer:A Variable in Java is something that holds a particular value in a class. For example:public class A { private String name = ""; ......} In the above declaration name is a variable. It would hold the data of type String.An Identifier is nothing but the name that we give for our variables, classes, methods etc. It is nothing but the name with which we identify an entity in Java. For example here A is the identifier for the class, name is the identifier for the variable etc.

Why does not unix use 0 as a valid process identifier?
0 is used as a Valid Process identifier. It is used as the PPID for /etc/init that starts everything on the server. The PPID Is the Parent Process Identifier. The Parent Process is Process 0, or the System Startup Process. All processes spawn from this PPID. PID 1 is /etc/init which starts up everything else.
