ICSE − Q & A

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
