(1) ( Looping Techniques: while() Loops )

Write a program segment that uses a single while() loop which executes its loop body five times, each time displaying a random digit from this set of values.

{ 1 , 2 , 3 , 4 , 5 , 6 }

(2) ( Looping Techniques: for() Loops )

Write a looping segment that uses a single for() loop to display the following message, according to these loop control settings.

Chicago

loop control variable: counter

control variable ( initial value ): 0

looping condition / sentinel value: counter <= 3

control variable step increment: 2

(3) ( Nested Looping Techniques )

Predict the output of the following program segment.

int i = 20, m = 10, n = 15, p = 30;

for (i = m; i < n; i += p)

{

m = i;

n = m + p;

m = n + 3 * p;

System.out.println("\t" + m + "\t"+ n + "\t" + p);

}
