Java programming errors

Question description

I am having several errors when I try to run my java program source code. I have 3 programs to run but in all 3 I have errors and I dont know how to fix them. I need your help so I can know how to fix these types of java errors.here is my source code for the first one:import java.util.Scanner;public class Ch3Proj6dxc4187{public static void main(String[] args){double BMRFemale, BMRMale;int weightInPounds, heightInInches, ageInYears, word;Scanner keyboard = new Scanner(System.in);System.out.println("Enter weight in pounds: ");weightInPounds = keyboard.nextInt();System.out.println("Enter height in inches: ");heightInInches = keyboard.nextInt();System.out.println("Enter age in years: ");ageInYears = keyboard.nextInt();System.out.println("Are you sedentary, somewhat active, active, or highly active?");word = keyboard.nextInt();BMRFemale = 655 + (4.3 * weightInPounds) + (4.7 * heightInInches) - (4.7 * ageInYears);BMRFemale = BMRFemale/230;BMRMale = 66 + (6.3 * weightInPounds) + (12.9 * heightInInches) - (6.8 * ageInYears);BMRMale = BMRMale/230;System.out.println("The amount of bars consumed by a female are: " + BMRFemale);System.out.println("The amount of bars consumed by a male are: " + BMRMale);double sedentaryFemale = BMRFemale + 0.2;double sedentaryMale = BMRMale + 0.2;double somewhatActiveFemale = BMRFemale + 0.3;double somewhatActiveMale = BMRMale + 0.3;double activeFemale = BMRFemale + 0.4;double activeMale = BMRMale + 0.4;double highlyActiveFemale = BMRFemale + 0.5;double highlyActiveMale = BMRMale + 0.5;if (BMRFemale == sedentaryFemale)sedentaryFemale = BMRFemale + 0.2;else if (BMRMale == sedentaryMale)sedentaryMale = BMRMale + 0.2;else if (BMRFemale == somewhatActiveFemale)somewhatActiveFemale = BMRFemale + 0.3;else if (BMRMale == somewhatActiveMale)somewhatActiveMale = BMRMale + 0.3;else if (BMRFemale == activeFemale)activeFemale = BMRFemale + 0.4;else if (BMRMale == activeMale)activeMale = BMRMale + 0.4;else if (BMRFemale == highlyActiveFemale)highlyActiveFemale = BMRFemale + 0.5;else if (BMRMale == highlyActiveMale)highlyActiveMale = BMRMale + 0.5;}}here is my source code for the second one:import java.util.Scanner;public class Ch3Proj5dxc4187{public static void main(String[] args){double BMRFemale, BMRMale;int weightInPounds, heightInInches, ageInYears;Scanner keyboard = new Scanner(System.in);System.out.println("Enter weight in pounds: ");weightInPounds = keyboard.nextInt();System.out.println("Enter height in inches: ");heightInInches = keyboard.nextInt();System.out.println("Enter age in years: ");ageInYears = keyboard.nextInt();BMRFemale = 655 + (4.3 * weightInPounds) + (4.7 * heightInInches) - (4.7 * ageInYears);BMRFemale = BMRFemale/230;BMRMale = 66 + (6.3 * weightInPounds) + (12.9 * heightInInches) - (6.8 * ageInYears);BMRMale = BMRMale/230;double Man, Woman;if (BMRMale == Man) {Scanner reader = new Scanner(System.in);System.out.println("Enter M for man: ");int n = reader.nextInt();}if (BMRFemale == Woman){System.out.println("Enter W for woman: ");System.out.println("The amount of bars consumed by a female are: " + BMRFemale);System.out.println("The amount of bars consumed by a male are: " + BMRMale);}}}here is my source code for the third one:import java.util.Scanner;public class Ch3Proj1dxc4187{public static void main(String[] args){Scanner in = new Scanner(System.in);System.out.println( "Enter price of an item: " );int price = in.nextInt();int change = 100 - price;int quarters = change/25;change = change % 25;int dimes = change/10;change = change % 10;int nickels = change/5;change = change%5;{if (price < 25)System.out.println("This is an error, cost under 25 cents!");else if (price > 100)System.out.println("This is more than a dollar.");else (!price.equals(5))System.out.println("This is not an integer multiple of 5!");}System.out.println("You bought an item for " + price + " cents and gave me a dollar so your change is:");    System.out.println("t" + quarters + " quarters,");    System.out.println("t" + dimes    + " dimes, and");    System.out.println("t" + nickels  + " nickels");}}
