Java basic Practical Programming (Part-1)

Question 1 ):- Enter second And it gives Output As Hours And Min.

class A
{
public static void main(String[] args) 
{
int Sec1,Min,Hours;
Sec1=Sec/60;
System.out.println("Sec IS:"+Sec1);
Min=((Sec%3600)/60);
System.out.println("Min IS:"+Min);
Hours=Sec/3600;
System.out.println("Hours IS:"+Hours);
}
}

    

Question 2 ):- Enter 3,5 And Both Divisible 3,5.

class A
{
public static void main(String[] args) 
{
for(int No1=1;No1<=20; No1++)
{
if (No1%3==0) 
{
System.out.println("No is"+No1);
}
if (No1%5==0) 
{
System.out.println("No is"+No1);
}
if (No1%3==0 && No1%5==0) 
{
System.out.println("No is"+No1);
}
}
}
}

Question 3 ):-Even No And NO is Divide BY 4.

class A
{
    public static void main(String[] args) 
    {
int mul=1,j=0;
for(int i=1;i<=20; i++)
    {
if (i%2==0) 
    {
System.out.println("EVEN No is"+i);
System.out.println();
j=i;
if(j%4==0)
    {
    System.out.println("NO Divide By 4 IS:"+j);
    mul=mul*j;
    }
    }
    }
System.out.println("Multiplication IS:"+mul);
}
}

Question 4 ):-Givan No Count How Many TIme Comes IN no.

class A
{
public static void main(String[] args) 
{
int No1=123;
if(No1%10==0 && No1/10==0)
{
System.out.println("NO IS:"+No1);
}
}
}

Question 5 ):-Enter Two and check no is Prime or Not.

import java.util.*;
class Prime
{
public static void main(String args[])
{
int i,No1,No2,flag;
Scanner s1=new Scanner(System.in);
System.out.println("Enter a No:");
No1=s1.nextInt();
System.out.println("Enter Second No:");
No2=s1.nextInt();
while(No1<No2)
{
flag=0;
for(i=2;i<No1;i++)
{
if(No1%i==0)
{
flag=1;
break;
}
}
if(flag==0)
{
System.out.println("Prime No IS:"+No1);
}
No1++;
}
}
}
