Generate Pascal Triangle in Java - Java Code for Pascal Triangle

It is a basic program to generate pascal triangle in Java language.

Pascal Triangle
It is a triangular array of the binomial coefficients in a triangle. Named Pascal comes from French mathematician, Blaise Pascal. In the program user input number. It generate rows for input number. In first row there is only the number 1. From all next rows, add the number directly above and to the left with the number directly above and to the right to find the new value.

Program Code

//Java Program to print Pascal Triangle
import java.util.*;
class Pascal 
{ 
 public static void main(String[] args) 
 { 
    System.out.print("Enter no of rows for pascal triangle: ");
    Scanner console=new Scanner(System.in);
    int num=console.nextInt();
    for (int i = 0; i < num; i++)
                  {
                        int c = 1;
 
                        for(int j = 0;j < num-i; j++)
                        {
                              System.out.print("   "); //blank space
                        }
 
                        for(int k = 0; k <= i; k++)
                        {
                              System.out.print("   ");
                              System.out.print(c); //print c value 
                              System.out.print(" ");
                              c = c * (i - k) / (k + 1);
                        }
    System.out.println();
                        System.out.println();
                  }
                  System.out.println();       
    }
}

C Program For Pascal's Triangle - Pattern Pascal's Triangle in C Programming

It is a triangle array of the binomial coefficients. In this program input value for rows of pascal's triangle.
To get element of particular location by adding upper level(above) left value and above right value.

Program Code

//C Program to generate pascal triangle
#include"stdio.h"
#include"conio.h"
void main()
{
 int num,c,i,j,k;
 clrscr();
 printf("\nenter number of rows for pascal triangle: ");
 scanf("%d",&num);
 printf("\n\t********PASCAL TRIANGLE********\n\n");
 for(i=0;i<num;i++)
 {
  c = 1;
  for(j=0;j<num-i;j++)
  {
   printf("   ");
  }
  for(k = 0;k<=i;k++)
  {
   printf("   ");
   printf("%d",c); 
   printf(" ");
   c = c * (i - k) / (k + 1);
  }
  printf("\n");
  printf("\n");
 }
 printf("\n");
 getch();
}

Fibonacci Series Program in Java Programming

It is a java program to generate Fibonacci series. In this program user input a number and prints the Fibonacci series for accepted number.

Java Fibonacci Series Program

Source Code

import java.lang.*;
import java.util.*;
class fibonacci
{
 public static void main(String arg[])
 {
        int a=0,b=1,c=0,i,num;
 Scanner scan = new Scanner(System.in);
 System.out.print("enter any number for fibonacci series:  ");
 num = scan.nextInt();
 System.out.println("Fibonacci Series is:"); 
 for(i=0;i<num;i++)
 {
  System.out.print(c+"\t");       
  a=b;
  b=c;
  c=a+b;
  }
 }
}

Output

In this java program create a class Fibonacci and use concept of Scanner class to accept a number from user. This program generate Fibonacci series for input.

Java is a Platform Independent Language

Meaning of Platform Independent

It means that a program of java language must be portable to other system. Java program must be run on any hardware, machine and any operating system.
Example: java mobile games
Java mobile games runs on any multimedia mobile. When we start a java game on mobile first automatically load java runtime environment. Then mobile able to run java game independently.

Why java is a platform independent language?

Java is platform independent language. When we compile java program then it makes source file to bytecode(class file).

Bytecode is a intermediate form which is closer to machine representation. Bytecode is certain and remain same for all platforms. When compile source code(program.java) is makes bytecode(program.class). Bytecode is faster then source code.
To run bytecode to any platform there is need to load java virtual machine(JVM) interpreter.
Before run java program need JVM must be loaded into particular system. JVM makes java runtime environment into system. Bytecode makes java as platform independent compilation.
