I need help writing code to convert 12-hour time formats to 24-hour time formats. ie "03:12 PM" to "15:12"

it needs to recall the methodInteger.parseInt()to take a string parameter and return the integer equivalent

precondition: the String value of the time parameter is valid and has a length of 8 characters.

here is the required base where amerFormat is 12 hour time:

public static String convertTime(String amerFormat)

{

}

I am also having trouble with solving this problem

"ThecalcCircleCircumf()method invoked within in theCircleStatsTesterclass is overloaded. Write the overloaded methods in the incompletepublic CircleStatsclass."

public class CircleStats

{

public CircleStats()

{

}

//...code goes here

}

public class CircleStatsTester

{

public static void main(String[] args)

{

int diameter = 5;

double radius = 2.5;

CircleStats cStats = new CircleStats();

System.out.println("The circumference = " + cStats.calcCircleCircumf(diameter));

System.out.println("The circumference = " + cStats.calcCircleCircumf(radius));

}

}
