Control Structures in java

  for  Repetition Statement

 The while statement can be used to implement any counter-controlled loop. Java also provides the for repetition statement, which specifies the counter-controlled-repetition details in a single line of code. 

1  //for loop
 2  //Counter-controlled repetition statement.

 4  public class ForCounter
 5  {
 6     public static void main( String args[] )
 7     {
 8        // for statement header includes initialization, 
 9        // loop-continuation condition and increment     
10        for ( int counter = 1; counter <= 10; counter++ )
11           System.out.printf( "%d  ", counter );

13        System.out.println(); // output a newline
14     } // end main
15  } // end class ForCounter

ADDING TWO NUMBERS WITH USER INPUT

// Addition program that displays the sum of two numbers.
import java.util.Scanner; // program uses class Scanner
  
public class Addition
   {
   // main method begins execution of Java application
 public static void main( String args[] )
  { // create Scanner to obtain input from command window 

   Scanner input = new Scanner( System.in );             

   int number1; // first number to add    

   int number2; // second number to add   

   int sum; // sum of number1 and number2

 System.out.print( "Enter first integer: " ); // prompt
 number1 = input.nextInt(); // read first number from user 

System.out.print( "Enter second integer: " ); // prompt 

 number2 = input.nextInt(); // read second number from user 

 sum = number1 + number2; // add numbers     

 System.out.printf( "Sum is %d\n", sum ); // display sum 

} // end method main 

} // end class Addition
