87.Write a program to enter any two numbers and display the greater one.


   import java.util.Scanner; 

class Greater 
{ 
   public static void main(String[] args) { 
       Scanner sc= new Scanner(System.in); 
       System.out.println("Enter First number"); 
       int a= sc.nextInt(); 
       System.out.println("Enter Second number"); 
       int b = sc.nextInt(); 
       if(a> b){ 
           System.out.println(a+"is greater"); 
       } 
       else{ 
           System.out.println(b+ "is greater"); 
       } 
        


   } 
}     

88. Write a program in java to enter any 15 numbers and print only those numbers which are divisible by 5 and 7.

 import java.util.*; 
    
   class Divisible{ 
   public static void main(String[] args) { 
   int[] num = new int[15]; 
   for (int i = 0; i   < num.length; i++) { 
   System.out.println("Enter number " + (i + 1)); 
   Scanner MyScanner = new Scanner(System.in); 
   num[i] = MyScanner.nextInt(); 
   } 
   for (int i = 0; i   < num.length; i++) { 
   if (num[i] % 5 == 0  & & num[i] % 7 == 0) { 
   System.out.println(num[i]); 
   } 
   } 
   } 
    
   } 
    
    
    
    

90. Write a program in java to generate the following series 1,23,456,78910.

 import java.util.Scanner; 
    
   class Pattern{ 
   public static void main(String[] args) { 
   int k=1; 
   for(int r=1;r  <=4;r++) 
   { 
   for(int c=1;c  <=r;c++) 
   { 
   System.out.print(k); 
   k++; 
   } 
   System.out.print(" "); 
   } 
   } 
   } 

91. Write a program in java to ask number and check whether the given no is prime or composite.

 class PrimeAndComposite{ 
   public static void main(String[] args) { 
   int num = 0; 
   System.out.println("Enter number"); 
   Scanner MyScanner = new Scanner(System.in); 
   num = MyScanner.nextInt(); 
   int count = 0; 
   for (int i = 1; i   <= num; i++) { 
   if (num % i == 0) { 
   count++; 
   } 
   } 
   if (count == 2) { 
   System.out.println("Number is prime"); 
   } else { 
   System.out.println("Number is composite"); 
   } 
   } 
    
   } 

92. Write a program in java to convert binary number to decimal number.

 class BinaryToDecimal{ 
   public static void main(String[] args) { 
   int num = 0; 
   System.out.println("Enter binary number"); 
   Scanner MyScanner = new Scanner(System.in); 
   num = MyScanner.nextInt(); 
   int dec = 0; 
   int i = 0; 
   while (num != 0) { 
   int rem = num % 10; 
   dec = (int) (dec + rem * Math.pow(2, i)); 
   i++; 
   num = num / 10; 
   } 
   System.out.println("Decimal number is " + dec); 
   } 
    
    
   } 

93. Write a program in java to ask any number and check whether the given number is Armstrong or not.

class Armstrong{ 
   public static void main(String[] args) { 
   int num = 0; 
   System.out.println("Enter number"); 
   Scanner MyScanner = new Scanner(System.in); 
   num = MyScanner.nextInt(); 
   int sum = 0; 
   int temp = num; 
   while (num != 0) { 
   int rem = num % 10; 
   sum = sum + (rem * rem * rem); 
   num = num / 10; 
   } 
   if (temp == sum) { 
   System.out.println("Number is Armstrong"); 
   } else { 
   System.out.println("Number is not Armstrong"); 
   } 
   } 
    
   } 

94. Write a program in java to print first ten multiples of ask number.

import java.util.*; 
    
   class Multiples{ 
   public static void main(String[] args) { 
   int num = 0; 
   System.out.println("Enter number"); 
   Scanner MyScanner = new Scanner(System.in); 
   num = MyScanner.nextInt(); 
   for (int i = 1; i   <= 10; i++) { 
   System.out.println(num * i); 
   } 
   } 
    
   } 

95. Write a program in java to ask three sides of a triangle and determine whether a triangle is right angled triangle or not.

 import java.util.*; 
    
   class Triangle{

   int c = 0; 
   System.out.println("Enter first side"); 
   Scanner MyScanner = new Scanner(System.in); 
   a = MyScanner.nextInt(); 
   System.out.println("Enter second side"); 
   b = MyScanner.nextInt(); 
   System.out.println("Enter third side"); 
   c = MyScanner.nextInt(); 
   if (a * a + b * b == c * c) { 
   System.out.println("Triangle is right angled"); 
   } else {
