ICSE − Q & A

Hey guys, pls tell me if this is correct: ICSE Specimen paper question 5 part 1 : is this solution correct: 
series 1 
{ 
public void main ( int x ) 
{ 
double sum= 0.0; 
for (i=4;i<=4*n;i+=4)
 { 
sum = sum+1.0/( double)i;
 } 
System.out.println("s="+sum); } 
}

state the data type and value of y after the following is executed 
char x = '7'
y=character.isLetter(x)

Where i can find important computer applications notes???

Math.random ()*2
Will it give either 1 or 0 when into??

WAP to find the nearest prime number to the number entered by the user

o Read all the instructions carefully and especially in section B, you must choose 4 best answers know and if time permits attempt the rest.
o	You must not switch over sections again and again  i.e. whichever section you began, you should complete it before switching to another section.
•	Any question found very easy, kindly read it at least 2 times to ensure that your reading and understanding are Tips to solve the paper-
o	matching
•	Theory Section (Section A - 40 marks)
.
o	Primitive data types: Memory size, data range, default value of each.
o	Operators: Unary, Binary and Ternary: Ternary operator(?:) is more important. Increment and decrement operators along with shorthand   operator. Like x += ++x - - x
o	Math.functions( )- output & Java Expression
o	String functions: .concat(), .substring(), .indexOf(), .startsWith(), .endsWith(), Character.toUpperCase() functions
o	User define functions & Constructor, class & object
o	Principles of Java: Encapsulation, Polymorphism, Abstraction, Inheritance.
o	Output of a nested loop/do-while
o	Implicit cast and explicit cast
o	Data conversion using .valueOf() or .toString()
o	Java token: Keywords, Identifier, Literal, Operator and punctuator
o	Errors in Java with reasons
o	Non-graphic characters
o	Operators precedence
o	 Write a function prototype.
o	Local variables, Instance variables and Static(class) variable
•	Programming Section (Section B - 60 mark)
•	
o	Functions & Constructor: Always one question on call by reference and call by value - Function overloading 
o	Switch-case with patters or series
o	Array search has good chances in this exam.
o	String
o	Modulus
HOPE SO IT WILL HELP
