Answer 1

Answer:

Here you go.Consider giving brainliest if it helped.

Explanation:

import java.io.*;//include this header for the file operation

import java.util.*;//to perform java utilities

import javax.swing.JOptionPane;//needed fro dialog box

class Driver{

  public static void main(String args[]){

      int wages[]=new int[15];//array to hold the wages

      int index=0;

      try{

          //use try catch for the file operation

          File file=new File("wages.txt");

          Scanner sc=new Scanner(file);//pass the file object to the scanner to ready values

          while(sc.hasNext()){

              String data=sc.nextLine();//reads a wage as a string

              String w=data.substring(1);//remove the dollar from the string data

              wages[index++]=Integer.parseInt(w);//convert the wage to int and store it in the array

          }

          sc.close();//close the scanner

      }catch(FileNotFoundException e){

          System.out.println("Error Occurrred While Reading File");

      }

     

      //sort the array using in built sort function

      Arrays.sort(wages);

      //print the wages

      System.out.println("Wages of 15 person in ascending order:");

      for(int i=0;i<wages.length;i++){

          System.out.print("$"+wages[i]+" ");

      }

      //call the increases wages method

      wages=increaseWages(wages);//this method return the updated wages array

     

  }

 

  //since we can call only static methods from main hence increaseWages is also static

  public static int[] increaseWages(int wages[]){

      //increase the wages

      for(int i=0;i<wages.length;i++){

          wages[i]+=500;

      }

     

      //print the new wages

      int sum=0;

      System.out.println("\n\nNew wages of 15 person in ascending order:");

      for(int i=0;i<wages.length;i++){

          sum+=wages[i];//sums up the new wages

          System.out.print("$"+wages[i]+" ");

      }

     

      //display the summation of the new wages in a dialog box

      JOptionPane.showMessageDialog(null,"Total of new wages: "+sum);

      return wages;

  }

}
