ICSE − Q & A

what is the audible bell(computer applications)

Write a program to check the validity of any entered character and print if it is an alphabet, digit or any other character.

Do we need to describe the variables for the  class program( the very first programme)?? variables and method are already described there...

Re write using for loop
int m=100;
while(true)
{
System.out.println(m/2);
m-=10; if(m%4==0)break;
}

Is this answe valid:
boolean v=true;

for(int m=100;v==true;m-=10)

{

 System.out.println(m/2);

 v=(m%4==0)?false:true;

}

Whats the output:-
s1 = "ABC";
s2 = "ABCD";

int n = s2.compareTo(s1);
System.out.println(n);

//STRICTLY NOT FOR EXAMINATION PURPOSES!

What do you mean by...sole trapping in football??

Is there no way to extract individual words from a string to perform various operations, expect by using array? I am confusion.

An interesting fact:

Are comment lines in Java programs executed by the compiler??
Add a response to that first and then scroll down,please.













//How are you
//Looking for the answer its coming

//\u000d System.out.println("A comment that executes");




Looking for the output:
A comment that executes




Confused,scroll down




Actually,when we use \u000d then what follows next is regarded as the next line in Java



So the code would have been clear if I would have written like this:


//\u000d
System.out.println("A comment that executes");



Enjoyed it after a nerve-racking day of Study??



Strictly not for exam purpose
and if then at your own risk.
