  • Using Java

Lecture 11 Repetition Statements Practices
Teacher Mahmoud Rafeek Alfarra
2
Practice 1
  • Identify and correct the errors in each of the
    following pieces of code.
  • int x 1,
  • total
  • while ( x lt 10 )
  • total x x

3
Practice 1
  • Identify and correct the errors in each of the
    following pieces of code.
  • while ( x lt 100 )
  • total x
  • x
  • while ( y gt 0 )
  • System.out.println( y )
  • y

4
Practice 1
  • Identify and correct the errors in each of the
    following pieces of code.
  • for ( i 100, i gt 1, i )
  • System.out.println( i )
  • The following code should output the odd integers
    from 19 to 1
  • for ( i 19 i gt 1 i 2 )
  • System.out.println( i )

5
Practice 1
  • Identify and correct the errors in each of the
    following pieces of code.
  • The following code should print whether integer
    value is odd or even
  • switch ( value 2 )
  • case 0
  • System.out.println( "Even integer" )
  • case 1
  • System.out.println( "Odd integer" )

6
Practice 1
  • Identify and correct the errors in each of the
    following pieces of code.
  • The following code should output the even
    integers from 2 to 100
  • counter 2
  • do
  • System.out.println( counter )
  • counter 2
  • While ( counter lt 100 )

7
Practice 2
  • Trace the following program

8
Practice 3
  • Trace the following program

9
Practice 3
  • Trace the following program

10
Practice 4
  • Trace the following program

11
Practice 5
  • Trace the following program

12
Practice 5
  • Trace the following program

13
Practice 6
  • Write an application that finds the smallest of
    several integers. Assume that the first value
    read specifies the number of values to input from
    the user.

14
Practice 7
  • Write an application that calculates the product
    of the odd integers from 1 to 15.

15
Practice 8
  • Write an application that prints the following
    diamond shape. You may use output statements that
    print a single asterisk (), a single space or a
    single newline character. Maximize your use of
    repetition, and minimize the number of output
    statements.
