3.WAP IN JAVA TO INPUT THREE NUMBERS AND COUNT HOW MANY OF THEM ARE EVEN .
import java.util.*;
class Prog
{
public static void main(String args[ ])
{
Scanner ob=new Scanner(System.in);
int x,y,z;
System.out.print(“Enter the numbers”);
x=ob.nextInt();
y=ob.nextInt();
z=ob.nextInt();
int count=0;
if((x%2)==0)
count+;
if((y%2)==0)
count+;
if((z%2)==0)
count+;
System.out.println(“Total Even numbers”+count);
}
}
2.WAP IN JAVA TO INPUT TWO NUMBERS AND DISPLAY THE LARGEST NUMBER AMONG THEM, IF BOTH THE NUMBERS ARE EQUAL , THEN DISPLAY A SUITABLE MESSAGE.
import java.util.*;
class Prog
{
public static void main(String args[ ])
{
Scanner ob=new Scanner(System.in);
int x,y;
System.out.print(“Enter the numbers”);
x=ob.nextInt();
y=ob.nextInt();
if(x==y)
System.out.println(“both the numbers are equal”);
if(x>y)
System.out.println(x+”is largest”);
else
System.out.println(y+”is largest”);
}
}
1.WAP IN JAVA TO INPUT A NUMBER AND CHECK WHETHER THE NUMBER IS ODD POSITIVE OR NOT.
import java.util.*;
class Prog
{
public static void main(String args[ ])
{
Scanner ob=new Scanner(System.in);
int num;
System.out.print(“Enter the number”);
num=ob.nextInt();
if((num>0)&&((num%2)!=0)))
System.out.println(num+”is Odd Positive”);
else
System.out.println(num+”is not Odd Positive”);
}
}
3. WAP IN JAVA TO INPUT PURCHASE AMOUNT FROM THE USER AND CALCULATE DISCOUNT AMOUNT FROM ON THE BASIS OF THE FOLLOWING :
IF PURCHASED AMOUNT IS UPTO Rs. 500 , DISCOUNT IS 10%
IF PURCHASED AMOUNT IS >Rs. 500 , BUT LESS THAN Rs.1000,
DISCOUNT IS 20%
IF PURCHASED AMOUNT IS IS GREATER THEN Rs. 1000 ,
DISCOUNT IS 30%
DISPLAY NETAMOUNT SHOULD PAY BY THE CUSTOMER .
import java.util.*; //import java packages
class Prog //declare the class
{
public static void main(String args[ ]) // “main” method
{
Scanner ob=new Scanner(System.in);
double pamt,discount,netamt; //declare the variable
System.out.print(“Enter Purchased Amount”); //input the value
pamt=ob.nextDouble( ) ;
if(pamt<=500)
discount=pamt*(10/100);
if((pamt>500) && (pamt<1000))
discount=pamt*(20/100);
if(pamt>=1000)
discount=pamt*(30/100);
netamt=pamt-discount;
System.out.prinln(“Net Amount payable”+discount); //display Discount Amount
System.out.prinln(“Net Amount payable”+netamt); //display Net Amount
} //end of “main”
} //end of class
2. WAP IN JAVA TO INPUT A NUMBER WHICH CONSIST OF THREE DIGITS , DISPLAY TOTAL NUMBER OF EVEN DIGITS FROM IT .
import java.util.*; //import java packages
class Prog //declare the class
{
public static void main(String args[ ]) // “main” method
{
Scanner ob=new Scanner(System.in);
int num; //declare the variable
System.out.print(“Enter the number”); //input the value
num=ob.nextInt( ) ;
int x1=num%10; //extract the digits
num=num/10 ;
int x2=num%10;
int x3=num/10;
int count=0;
if((x1%2)==0) //check for Even digits and Count
count++;
if((x2%2)==0)
count++;
if((x3%2)==0)
count++;
System.out.prinln(“Total Even digits :”+count); //display total number of digits
} //end of “main”
} //end of class
1. WAP IN JAVA TO INPUT A NUMBER WHICH CONSIST OF TWO DIGITS AND DISPLAY AVERAGE OF THE DIGITS.
import java.util.*; //import java packages
class Prog //declare the class
{
public static void main(String args[ ]) // “main” method
{
Scanner ob=new Scanner(System.in);
int num; //declare the variable
System.out.print(“Enter the number”); //input the value
num=ob.nextInt( ) ;
int x1=num%10; //extract the digits
int x2=num/10 ;
double avg=(double)((double)(x1)+(double)(x2))/2; //calculate average
System.out.println(“Average of the digits :”+avg); //display the average
} //end of “main”
} //end of class
4. WRITE AN ALGORITHM TO INPUT 100 NUMBERS AND DISPLAY THE SUM OF
FACTORS OF EACH NUMBER.
START
STEP 1 : DECLARE I ,J, C , NUM AS AN INTEGER
STEP 2: I=1 , NUM=0
STEP 3: INPUT "ENTER THE NUMBER", NUM
STEP 4: J=1 , C=0
STEP 5: IF NUM%J=0 THEN C=C+J
STEP 6: INCREMENT THE VALUE OF J BY 1
STEP 7 : IF J<=NUM THEN GOTO STEP 5
STEP 8 : PRINT "SUM OF FACTORS", C
STEP 9: INCREMENT THE VALUE OF I BY 1
STEP 10: IF I<=100 THEN GOTO STEP 3
END
