Q1.A person has n number of sons and n square number of cows.Each cow gives milk as per their serial number. For example cow number 1 gives 1 liter milk, cow number 2 gives 2 liter of milk and so on.Write a program in bluej(java) to solve the above problem
Solution 1:
class cows { public void abc(int n) { int cows=n*n; int a[][]=new int [n][n]; for(int i=0;i{ a[i][i]=i+1; } int d=n; for(int j=0;j{ for(int k=0;k{ if(j!=k) { a[k][j]=d+1; d=d+1; } } } for(int p=0;p{ int w=p+1; System.out.print(w+"number son will get cows with serial numbers"); for(int q=0;q{ System.out.print(a[p][q]+","); } System.out.println(" "); } } } ** Input number of sons:5 ** Output number of cows:1number son will get cows with serial numbers1,10,14,18,22, 2number son will get cows with serial numbers6,2,15,19,23, 3number son will get cows with serial numbers7,11,3,20,24, 4number son will get cows with serial numbers8,12,16,4,25, 5number son will get cows with serial numbers9,13,17,21,5,
Q2.Program to find out the co prime numbers written in Bluej(java)
Solution 2: class AP {int s; public void abc(int a,int b,int n) { if(a>b) { for(int i=1;i<=b;i++) { if(a%i==0) { s=s+1; } } if(s==0) { System.out.println("The numbers are coprime"); for(int j=0;j{int k=a+j*b; System.out.print(k); } } } else { for(int i=1;i<=a;i++) { if(b%i==0) { s=s+1; } } if(s==0) { System.out.println("The numbers are coprime"); for(int j=0;j{ int k=b+j*a; System.out.print(k); } } } } }
