plz explain

BufferedReader b = new BufferedReader(new InputStreamReader(System.in)); ArrayList s = new ArrayList(); for(int a=0; a<10; a++) { s.add(b.readLine()); } ArrayList result = doubleValues(s); for( String x: result)

public class Friend { String name; int age; char sex; public void initialize(String name){ this.name = name; } public void initialize(String name , int age){ this.name = name; this.age = age; } public void initialize(String name , int age, char sex){ this.name =

so far 'm abl to write code upto this. condition 3 needs solution in this, i read other soutions but unable to understand them. BufferedReader b = new BufferedReader(new InputStreamReader(System.in)); ArrayList l = new ArrayList(); for(int i=0; i<5; i++) {

package com.codegym.task.task05.task0532; import java.io.*; /* Task about algorithms */ public class Solution { public static void main(String[] args) throws Exception { BufferedReader reader = new BufferedReader(new InputStreamReader(System.in)); int maximum = 5; /

??
