Answer 1

with java 8+ you can try this code below:

import java.util.*;
import java.util.stream.Collectors;
public static void InsertionSort()
{
    System.out.println(processList.get(0).name);
    System.out.println(processList.get(1).name);
    System.out.println(processList.get(2).name);
    
    processList=processList.stream()
    .sorted((o1,o2)->{return o1.priority-o2.priority;})
    .collect(Collectors.toList());
    
    System.out.println(processList.get(0).name);
    System.out.println(processList.get(1).name);
    System.out.println(processList.get(2).name);
}

Answer 2

Use List#set to set an element at an index.

processList.get(j+1).priority = processList.get(j).priority; 

becomes

 processList.set(j+1, processList.get(j));

And

processList.get(j + 1).priority = key; 

becomes

processList.set(j+1, processList.get(i));
