Question

The following individual two programs are using while loop in order to print a specific output:

The outputs of the first program are:

10

9

8

5

4

The outputs of the second program are:

123456789

Using the Table 3.1 below, allocate the error(s) of each line of two programs and type of error:

The first program:

1. public Main
2. {
3. public static void main(String args[]){
4. int i=10
5. while(i>4){
6. System.out.print(i);
7. i++;
8. }
9. }
10. }

The second program:

11.   public class Main
12.   {
13.   public static void main(String args[]){
14.   int i=10;
15.   while(i<1){
16.   System.out.println(i);
17.   i--;
18.   }
19.   }
20.   }

Table 3.1

Line Number	Error	Type of error(logical error or Syntax error)
1	Miss word class	Syntax error
2	no	no

Answer 1

Program:

public class Main
{
public static void main(String args[]){
int i=10;
while(i>=4){
if(i!=6 && i!=7)// Here checking the i value equals to 6 or 7
{
System.out.println(i);// Here this statement is printed if above condition is True
}
i--;// Here decrementing the value of i
}
}
}

Output:

Program:

public class Main
{
public static void main(String args[]){
int i=1;
while(i<10){ // Here checking the i value equals to 10
System.out.print(i);// Here this statement is printed if above condition is True
i++;// Here incrementing the value of i by 1
}
}
}

Output:

Line Number	Error	Type of error(logical error or Syntax error)
1	Miss word class	Syntax error
2	no	no
3	no	no
4	';' expected	Syntax error
5	no	no
6	no	no
7	no	no
8	no	no
9	no	no
10	no	no
