if(age > 64 )

System.out.print("Senior voter");

if(age < 18 )

System.out.print("Under age");

if(age >= 18 && age < 65 )

System.out.print("Regular voter");

8.The following code fragment is supposed to print out the values 25, 60, and 8, in

that order. Instead, it prints out 50, 60, and 4. Why?

length = 25 ;

width = 60 ;

if(length = 50 )

height = 4 ;

else

height = 8 ;

System.out.print(""+ length + " "+ width + " "+ height);

9.The following Java code segment is almost unreadable because of the

inconsistent indentation and the random placement of left and right braces. Fix

the indentation and align the braces properly.

// This is a nonsense program segment

if(a > 0 )

if(a < 20 )

{

System.out.print("A is in range.");

b = 5 ;

}

else

{

System.out.print("A is too large.");

b = 3 ;

}

else

System.out.print("A is too small.");

System.out.print("All done.")

10.Given the floatvariables x1,x2,y1,y2, and m, write a code segment to find the
slope of a line through the two points (x1,y1) and (x2,y2). Use the formula

m= y2– y^1

x2– x 1
