I recently realized that 'System.out.println()' is a great example of function overloading.

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)); }

What's the use of static guys?

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?

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));

Guys all of you must have faced the problem of printing a particular array as it requires the user to type out another for loop which is time consuming tedious and boring
heres a trick but u ll have to import java's utilility package by import java.util.*
just say u wanna print array named arr
type :- System.out.println(Arrays.toString(arr));
the output is like this : [a,b,c,d] try this one out

If z=13,y=10,a=100.
Find a/=z++ + ++z*(- -y  -  y- -)%3 + z++ - ++y;

is Math.random(), shift and bitwise operators included in the syllabus?
