ICSE − Q & A

Aim at the stars even if you fail you will land on the moon(or an alien planet or white hole or whatever you like).

The bodyless loop whose function in the book is given that"It is used to create delay" is actually not taken as a delay for humans as the i9 7980x processor overclocked at 4.6GHz processes it so quickly that hardly i can see any delay
but if you actually want a delay u can use



Thread.sleep(1000);//here 1000 means 1 second delay 


time is given inside the brackets is in milli-seconds

but whenever u use it dont forget to wrap this function with try-catch block




try{
Thread.sleep(1000);
}
catch(InterruptedException e){
System.ot.println("Technical Problem");
}

Oh! I have a trick for arrays too.

lets assume we have an array named arr
then 
for(i:arr)
{
System.out.println(i);//Here i have just printed the elements but you can do anything
}
//Here each time when the loop runs the i contains the next element of the array cell

which means if arr[] would be{1,7,10,99,-10}
i will have the value 1 in first execution of the for loop
then i will have value 7 in next loop and so on....
comment if you liked?

Any Whovians here??

into m,n,p,q= 0;
for(m=2;m<=3;++m)
{
    for(n=1;n<=m;++n)
         { 
              p=m+n;
              if(p%3==0)
              q=q+p;
              else
              q=p+4;
           }
    }
System.out.println("Q="+q);

To get a random integer in the range [min, max),
int randomInt(int min, int max) {
    return Math.floor(min + (Math.random() * (max - min)));
}

To get a random double in range [min, max):
double randomDouble(int min, int max) {
    return min + (Math.random() * (max - min));
}

In how much time do you plan to complete your Computer paper's section A?

ok for patteren like this 
i
ic
ics
icse
we normally use two for loops but there is shor cut . here it is 
String nm = "icse";
for (int i = 1 ; i<=nm.length();i++)
s.o.p(nm.substring(0,1));

Do we need to learn the randes of data value like 0-38924789 this crppy table wich is present in tb
