Java Programming Lab Code

The java program find sum of  integers.       Pseudocode of sum of integer  set sum =0 Read an integer N initialize integer array size of N for n= 0  to N-1       Read an integer data      store data into array end for      for each E  in  array      sum = sum + E end each print sum Java keywords and objects usage in the program BufferedReader class object : provides stream mechanism to read inputs from user/keyboard Integer class object : converts string object into java primitive datatype int for-loop :- repeats reading inputs from user upto N times for-each  : to read element from array in sequential order  import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; public class SumofArrayNumber { public static void main(String[] args) throws IOException   ...

Add two numbers The java code add two numbers which are given as input to the code. The buffered reader object instance initialized to read the inputs from keyword. package cljavabasics; import java.io.BufferedReader; import java.io.DataInputStream; import java.io.IOException; import java.io.InputStreamReader; public class StreamInput { public static void main(String[] args) throws IOException { InputStreamReader dis = new InputStreamReader ( System.in ); BufferedReader br = new BufferedReader(dis); System.out.println( "Sum of Two Numbersn" ); System.out.println( "Enter first value" ); String arg1 =br.readLine(); int a = Integer.parseInt(arg1); System.out.println( "Enter second value" ); String arg2 =br.readLine(); int b = Integer.parseInt(arg2); int c= a+b; System.out.println( "ans : " + c ); } } Output Sum of Two Numbers Enter first value 30...
