6. Convert the following code to Ternary Operator.
if(a>=b && a<c)
System.out.println(a+b);
else
System.out.println(a*b);
7. Find the output of the following code.
if(1 + 1 + 1 + 1 + 1 == 5)
{
System.out.print("TRUE");
}
else
{
System.out.print("FALSE");
}
8. Find the output of the following code.
class Solution{
public static void main()
{
int i;
for(i = 1; i < 6; i++)
{
if(i > 3)
continue;
}
System.out.println(i);
}
}
9. What does the following code do?
int i, s;
s = 0;
for(i=1; i<=10; i++)
{
if(10%i==0)
{
s=s+i;
}
}
System.out.println(s);
10. Find the error in the following code.
Int i=10;
while(i>=1);
{
System.out.println(i*10);
i=i-1;
}
11. A class Numbers contains the following data members and member functions to check for the triangular numbers. [A triangular
number is formed by the addition of a consecutive sequence of integers starting from 1.]
For example,
1 + 2 = 3
1 + 2 + 3 =6
1 + 2 + 3 + 4 =10
1 + 2 + 3 + 4 + 5 = 15
Therefore 3, 6, 10, 15 are triangular numbers.
