Question

Find the error in each of the following code segments and explain how to correct it.

1. x = 1;

while ( x <= 10 );

x++;

}

2. for ( y = .1; y != 1.0; y += .1

System.out.println( y );

3. switch ( n ) {

case 1:

System.out.println( “The number is 1” );

case 2:

System.out.println( “The number is 2” );

break;

default:

System.out.println( “The number is not 1 or 2” );

break;

}

4. The following code should print the values 1 to 10.

n = 1;  

while ( n < 10 )

System.out.println( n++ );

Answer 1

x = 1;

E1 - while ( x <= 10 ); //There shouldn't be semi colon after while loop
Correction - while (x<=10)
E2 - //there was no opening bracket for while loop
Correction - {   
  
x++;

}

E3 - for ( y = .1; y != 1.0; y += .1 //Here, initialize y as float, and close the for loop bracket

Correction - for (float y=.1; y!=1.0; y+=.1)

E4 - for loop flower bracket missing
Correction - {
System.out.println( y );

switch ( n ) {

case 1:

System.out.println( “The number is 1” );
E5 - //break statement is missing
Correction - break;
case 2:

System.out.println( “The number is 2” );

break;

default:

System.out.println( “The number is not 1 or 2” );

break;

}
}

//The following code should print the values 1 to 10.

n = 1;

while ( n < 10 )
E6 - Flower bracket missing
Correction - {
System.out.println( n++ );
}
