hey guys im new to java(just starting it in uni)
i need some help in reading keyboard input.

i've got this so far:


int i;

int count;

System.out.println("Enter a number: \n");

//this is where the scan is ment to be

if((count<0 || count count >50

System.out.println("error.");

else

{

for(i=0;i<count;i++);

{

System.out.println("count is:") //how do i call the value of the i int the print?

}

}

also would a switch case statement work the same as in c?

thanks in advance

taking input:


Scanner scanner = new Scanner(System.in); // import java.util.Scanner if it complains

System.out.println("type something");

String something = scanner.nextLine();

System.out.println("you typed: " + something);

System.out.println("give number: ");

int number = scanner.nextInt();

Sample switch case statement:


int number = 3;

switch(number){

    case 1: System.out.println("The number is 1"); break;

    case 2: System.out.println("The number is 2"); break;

    case 3: System.out.println("The number is 3"); break;

    default: System.out.println("No idea what the number is, it's not 1, 2 or 3");

}
