- Write a program to input 10 numbers into an integer array and find the average of two-digit numbers only.
import java.util.Scanner;
class JavaTest1 {
public static void main(String argc[]) {
Scanner sc = new Scanner(System.in);
int a[] = new int[10];
int i, s = 0, c = 0;
System.out.println("Enter 10 numbers:");
for (i = 0; i < a.length; i++) {
a[i] = sc.nextInt();
if (a[i] >= 10 && a[i] <= 99) {
s = s + a[i];
c++;
}
}
if (c > 0)
System.out.println("Average of 2-digit numbers:" + (float) s / c);
else
System.out.println("No 2-digit numbers present");
}
}
2. Write a program to input 10 numbers into an integer array and print the position of the largest number.
import java.util.Scanner;
class JavaTest2 {
public static void main(String argc[]) {
Scanner sc = new Scanner(System.in);
int a[] = new int[10];
int i, l = 0;
System.out.println("Enter 10 numbers:");
for (i = 0; i < a.length; i++) {
a[i] = sc.nextInt();
if (i == 0)
l = a[i];
if (a[i] > l)
l = a[i];
}
System.out.println("Positions, where largest number is present, are:");
for (i = 0; i < a.length; i++) {
if (a[i] == l)
System.out.print(i + " ");
}
}
}
Enter 10 numbers:
12 23 45 66 534 56 35 5 3 55
Positions, where largest number is present, are:
4
3. Write a program to initialize the seven wonders of the world along with their location in two different arrays. Search for a name of the country input by the use. If found, display the name of the country along with its wonders, otherwise display "Sorry Bot Found" .
Seven Wonders : - Chichen Itza,Christ Redeemer,Taj Mahal, The Great Wall of China,Machu Picchu,Petra,Colosseum
Location : - Mexico,Brazil,India,China,Peru,Jordan,Italy
import java.util.Scanner;
class JavaTest3 {
public static void main(String argc[]) {
Scanner sc = new Scanner(System.in);
int i =0;
String wonders[] ={"Chichen Itza","Christ Redeemer","TajMahal", "The Great Wall of China","Machu Picchu","Petra,Colosseum"};
String location[] = {"Mexico","Brazil","India","China","Peru","Jordan","Italy"};
System.out.println("Enter Country name ");
String country = sc.nextLine();
boolean flag =false;
for(i=0;i<wonders.length;i++){
if(location[i].equalsIgnoreCase(country)){
flag =true;
break;
}
}
if(flag==true){
System.out.println(wonders[i]+"--"+location[i]);
}else{
System.out.println("Sorry Not Found");
}
}
}
Output :
Enter Country name
china
China--The Great Wall of China
4. Write a program to input five names in an array. Arrange these names in descending order of alphabets, using bubble sort technique.
import java.util.Scanner;
class JavaTest1 {
public static void main(String argc[]) {
Scanner sc = new Scanner(System.in);
int i =0;
String names[] = new String[5];
String temp;
for(i=0;i<names.length;i++){
System.out.println("Enter name");
names[i]= sc.nextLine();
}
int comLength =names.length-1;
for(i=0;i<comLength;i++){
for(int j=0;j<comLength-i;j++){
if(names[j].compareToIgnoreCase(names[j+1])<0){
temp = names[j];
names[j] =names[j+1];
names[j+1]=temp;
}
}
}
System.out.println("After sorting");
for(i=0;i<names.length;i++){
System.out.println(names[i]);
}
}
}
Enter name
anjan
Enter name
amit
Enter name
debadittya
Enter name
suman
Enter name
suresh
After sorting
suresh
suman
debadittya
anjan
