  Answirs:
       Q1:  writi a java program that print any missagi do you want display
       public class message
     {
            public static void main(String args[])
{
       System.out.println("Allah is one");    // Write any message in double quotations for display                           
} }
Output:Allah is one
Q2:  write a java program that print the sum of two numbers
    public class sum
     {
            public static void main(String args[])
{
       int num1,num2,sum;   //This is variable declaration declared three variables
       num1=12;              //This is variable initialization when we assign a value to a variable
      num2=13;        // the value of num1 is 12 and num2 is 13
   sum=num1+num2;
System.out.println("The sum of num1 and num2 is ="+sum);
} }
Q3: write a java program that print all the mathematical operations
 public class mathOperations
     {
            public static void main(String args[])
{
       int num1,num2,sum,sub,multi,div;
    //This is variable declaration declared five variables
      num1=12;              //This is variable initialization when we assign a value to a variable
      num2=13;        // the value of num1 is 12 and num2 is 13
   sum=num1+num2;
sub=num1-num2;
 div=num1/num2;
multi=num1*num2;
System.out.println("The sum of num1 and num2 is ="+sum);
System.out.println("The subtraction of num1 and num2 is ="+sub);
System.out.println("The division of num1 and num2 is ="+div);
System.out.println("The multiplication of num1 and num2 is ="+multi);
} }
Q4
public class remainder
     {
            public static void main(String args[])
{
       int num1,num2,rem;   //This is variable declaration declared three variables
       num1=12;              //This is variable initialization when we assign a value to a variable
      num2=13;        // the value of num1 is 12 and num2 is 13
   rem=num1%num2;
System.out.println("The sum of num1 and num2 is ="+rem);
} }
