Question

 You must find and correct all bugs in the following code, Put a comment in for each bug you find and then correct the error. The program must be fully debugged so that it compiles and has NO runtime or logic errors.  

 // Arrays.java // Debugging - put a comment in for each error found and // explain what is wrong.  You must fix all errors so that // the program compiles and runs without any errors.  public class Arrays  {    public static void main( String args[] )    {                int number;       int array[][] = { { 1, 2, 3 }, { 4, 5 }, ( 15 19 21 ) };                // loop through array's rows       for ( row = 1; row <= array.length(); row++ )        {          // loop through columns of current row          for ( column = 1; column < array.length; column++ );             array[ row ][ column ] += number;             System.out.print( array )           System.out.println(); // start new line of output       } // end outer for                      String Names = { Bart, Lisa, Maggie, Marge, Homer };       for( index = 0, index, < names, index++ )         System.out.println( names[ index1 ] );                int number1 = 0, number2 = 2, number3 = 4;       double result = 2.0 * number2 / number1;       number += number3;       System.out.println( result );       System.out.println( number );          } // end main } // end class Arrays 

Explanation / Answer

Here you go :)

please comment if you have any doubts

public class Arrays
{
public static void main( String args[] )
{
  
int number;
int array[][] = { { 1, 2, 3 }, { 4, 5 },{15,19,21} }; // wrong initilization   

number=5;
// loop through array's rows
for ( int row = 0; row < array.length; row++ ) // there is no method length() for array objects, its length field that returns the no of elements.
{
// loop through columns of current row
for ( int column = 0; column < array[row].length; column++ ) // ; closes the for loop
{ array[ row ][ column ] += number;
System.out.print( array[row][column]+" " );
}

System.out.println(); // start new line of output
} // end outer for
  
  
String[] Names = { "Bart", "Lisa", "Maggie", "Marge", "Homer" };//string objects needs to be in "" and its an array so []
for( int index = 0; index< Names.length; index++ ) // inappropriately placed , in place of ;
   //its Names not names
   //and length to get the size of array
System.out.println( Names[ index ] ); //index not index1
  
int number1 = 0, number2 = 2, number3 = 4;
  
double result = 2.0 * number2 / number1;
number=0;
number += number3; //need to initialize number before using it
System.out.println( result );
System.out.println( number );

} // end main
} // end class Arrays
