/*PROG 19.18 FINDING EXECUTION TIME OF A CODE SEGMENT */

class JPS18

{

public static void main(String[] args)

{

long start = System.currentTimeMillis();

for (int i = 0; i < 10000000; i++) {

}

long end = System.currentTimeMillis();

long exec_time = end-start;

System.out.println(“\nExecution time := “

+exec_time);

}

}

OUTPUT:

Execution time: = 938

Explanation: The method currentTimeMillis() returns the current time in milliseconds. Before

the execution of the for loop, starting time is stored in start . The ending time is stored in the end . The

difference of these ...
