Question. ticket sold to charity event

// You are using Java import java.util.*; import java.io.*; class Ticket{ public static void main(String ar[]){ int x,y,c,a,s; Scanner sc = new Scanner(System.in); x=sc.nextInt(); y=sc.nextInt(); c=(y-(5*x))/13; a=c+x; s=2*c; System.out.println("Number of children tickets sold : "+c); System.out.println("Number of adult tickets sold : "+a); System.out.println("Number of senior tickets sold : "+s); } }

2. Display the ascii vaue

// You are using Java import java.util.*; class Main{ public static void main(String ar[]){ char ch; Scanner sc = new Scanner(System.in); ch=sc.next().charAt(0); if((ch>='a'&&ch<='z')||(ch>='A'||ch<='Z')){ int a = (int)ch; float b = (float)ch; byte c=(byte)ch; short s = (short)ch; System.out.println("int:"+a); System.out.println("float:"+b); System.out.println("byte:"+c); System.out.println("short:"+s); } else{ System.out.println("Invalid"); } } }

3. Be it a last minute get together, a birthday party or corporate events... the "Pine Tree" Event Management Company helps you plan and execute it better and faster.

import java. util.*; import java. io.*; class Eventdetails { public static void main(String[] args) { String name, type; double expenses; int number; char entry; Scanner sc = new Scanner(System. in); name = sc. nextLine(); type = sc. nextLine(); number = sc. nextInt(); entry = sc. next() . charAt(0); expenses = sc. nextDouble(); System. out. println("Event Name : "+name); System. out. println("Event Type : "+type); System. out. println("Expected Count : "+number); System. out. println("Paid Entry : "+entry); System. out. println("Projected Expense : "+expenses+"L"); } }

4. Jeevan is running a sports club.

import java.util.*; class Main{ public static void main(String[] args){ int a, b, c; Scanner sc=new Scanner(System. in); a=sc . nextInt(); b=sc. nextInt( ); c=a+b; System. out. print(c); } }

5. Write a simple code by declaring three variables where two variables of integer type and one variable in double.

import java. util. Scanner; class Main{ public static void main(String args[]) { int x, y; double z; Scanner sc=new Scanner(System. in); x=sc. nextInt( ); y=sc . nextInt( ); z=x+y; System. out. printIn(z); } }

6. Write a program to display a string in following format.

import java. util. Scanner; class Main { public static void main(String[] args) { Scanner sc=new Scanner(System. in); String N; N=sc. nextLine(); String m; m=sc. nextLine( ); System. out. println(N +" and "+ m); } }

7. Write a program to calculate the simple interest.

import java. util. Scanner; class Main{ public static void main(String[] args){ Float a, b, d, c; Scanner sc=new Scanner(System. in); a=sc. nextFloat(); b=sc. nextFloat( ); d=sc. nextFloat( ) ; c=(a*b*d)/100; System. out. print(c); } }

8. Ram is new to Java Programming, So help Ram to print the word that he gives as input.

import java. util. Scanner; class Main { public static void main(String[] args) { Scanner sc=new Scanner(System. in); String s; s=sc. nextLine(); System. out. printIn("" +s); } }

Challange yourself

1. Ram is new to Java Programming, So help Ram to print the word that he gives as input.

//challange import java. util. Scanner; class Main { public static void main(String[] args) { Scanner sc=new Scanner(System. in); String s; s=sc. nextLine(); System. out. printIn("" +s); } }

2. Write a program to print the size of Integer, Float, and Double.

class Main{ public static void main(String ar[ ]){ System. out. printin("Integer = "+Integer. BYTES); System. out. printIn("Float = "+Float. BYTES); System. out. printIn( "Double = "+Double. BYTES); } }

3. Write a program to convert Celsius to Fahrenheit formula, F = 1.8 C + 32.

import java. util. Scanner; class Main public static void main(String[] args){ double a, b; Scanner sc=new Scanner(System. in); a=sc . nextFloat( ) ; b=1.8*a + 32; System. out.print(b); } }
