4. What is the output of the following Java code?
num = 1;

while (num < 10)
{

System.out.print(num + " ");
num = num + 2;

}

System.out.println();

5. When does the following while loop terminate?
ch = 'D';

5

while ('A' <= ch && ch <= 'Z')
ch = ( char )(( int )(ch) + 1));

Suppose that the input is:
38 35 71 14 -1
What is the output of the following code? Assume all variables are properly
declared.
sum = console.nextInt();
num = console.nextInt();

6.

for (j = 1; j <= 3; j++)
{

num = console.nextInt();
sum = sum + num;

}

System.out.println("Sum = " + sum);

Suppose that the input is:
38 35 71 14 -1
What is the output of the following code? Assume all variables are properly
declared.
sum = console.nextInt();
num = console.nextInt();

7.

while (num != -1)
{

sum = sum + num;
num = console.nextInt();

}

System.out.println("Sum = " + sum);
