Sample Program 1:

File  Name:  Array.java
Description:  This  program  uses  array
Output: Multiplying a number to itself with out using input stream reader
Program:

public  class  Array{
public static void main(String[] args){ int [] A = new int [5];
int [] B = new int [5]; for (int x=0; x<A.length; ++x){

A[x] = Integer.parseInt(args[x]); B[x] = A[x] * A[x];
System.out.println(B[x]);
}
}
}
 

Sample Program 2:

File  Name:  Array2.java
Description: This program uses array Output: multiplying a number to itself
Program:

import  java.io.*;

public  class  Array2{

public static void main(String[] args) throws IOException{
InputStreamReader isr = new InputStreamReader(System.in);
BufferedReader br = new BufferedReader(isr); int[] A = new int[5];
int[] B = new int[5]; String s;
for(int x=0; x<A.length;++x){ System.out.print("Enter" + (x+1) + "number: ");

s  =  br.readLine();
A[x]  =  Integer.parseInt(s);
}
System.out.println();

for(int x=0;x<A.length;++x){ B[x] = A[x] * A[x]; System.out.println(B[x]);

}
}
}
 

Sample Program 3:

File  Name:  Array3.java
Description: This program combined InputStreamReader and BufferedReader in one line
Output:  multiplying  a  number  to  itself
Program:

import  java.io.*;

public  class  Array3{

public static void main(String[] args) throws IOException{
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
int[] A = new int[5]; int[] B = new int[5]; String s;
for(int x=0; x<A.length;++x){ System.out.print("Enter " + (x+1) + " number: ");
A  [x]  =  Integer.parseInt(br.readLine());

}
System.out.println();

for(int x=0;x<A.length;++x){ B[x] = A[x] * A[x]; System.out.println(B[x]);

}
}
}
