}

 

 

4. What is the value of x after the following code:
			  			  
x=5;
while (x>=3)
     x=x/0;
	 

infinite loop, never ends compile time error runtime error x=5 x=0

 

5. What is the value of x after the following code:

x=50;
for (int i=5;i>=3; i--)
     x-=i;

 

6. What will be printed after the following code:

for (int i=0;i<=3; i++)
{
    for (int x=i; x < i+2; x++)
		System.out.print(x);
    System.out.print("_");
}
