Day-41:Array Task

[Lomanu4]

Task:
1) Use scanner class to get your name and print it.


package Array;

import java.util.Scanner;

public class InputTest2 {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("Tell Me your name ");
String name = scanner.nextLine();
System.out.println("Welcome to Java "+ name);
}
}

output:
Tell Me your name
pavithra
Welcome to Java pavithra

2) Using scanner class, get 5 subjects marks as float and calculate Total, Percentage


package Array;

import java.util.Scanner;

public class Task2 {
public static void main(String[] args) {

Scanner sc = new Scanner(System.in);
float[] marks = new float[5];
float total=0;

for(int i=0; i < marks.length; i++ ) {
System.out.println("Enter Mark:");
marks = sc.nextInt();
total=total+marks;


}
float percentage=(total/500)*100;
System.out.println("total:"+total);
System.out.println("percentage:"+percentage);
}

}

Output:


Enter Mark:
90
Enter Mark:
80
Enter Mark:
85
Enter Mark:
99
Enter Mark:
98
total:452.0
percentage:90.4

3) Create an array as below
int[] ar = new int[5];
Use for loop and print values of this array. Observe the result


package Array;
import java.util.Scanner;
public class Task3 {

public static void main(String[] args) {


int[] ar = new int[5];

for (int i = 0; i<=ar.length; i++) {
System.out.println("enter you number: " +i);

}
}

}

Output:


enter you number: 0
enter you number: 1
enter you number: 2
enter you number: 3
enter you number: 4
enter you number: 5

4)int[] marks = new int[5];
Get Marks from user (using Scanner) and store it in array. Print the values in reverse order. i.e., from last index to first index.


package Array;

import java.util.Scanner;

public class Task4 {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
// Get Marks from user (using Scanner) and store it in array. Print the values in reverse order. i.e., from last index to first index.
int[] marks = new int[5];

for (int i = 0; i < marks.length; i++) {
System.out.println("Enter your marks: ");
marks = sc.nextInt();



}
for (int j = marks.length-1; j >=0; j--) {
System.out.println(marks[j]);
}
}
}

Output:


Enter your marks:
90
Enter your marks:
80
Enter your marks:
70
Enter your marks:
60
Enter your marks:
87

87
60
70
80
90

Notes:


package Array;


import java.util.Scanner; // Import Scanner class from java.util

public class InputTest {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in); // Create Scanner object
System.out.println("Enter Mark:");
int mark1 = scanner.nextInt(); // Read integer input
System.out.println("hi " + mark1); // Print the input value
}
}

Output:
Enter Mark:
90
hi 90

Notes2:


package Array;

import java.util.Scanner;

public class InputTest2 {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("Tell Me your name ");
String name = scanner.nextLine();
System.out.println("Welcome to Java "+ name);
}
}

Output:
Tell Me your name
pavithra
Welcome to Java pavithra

Notes3:


package Array;

public class Mark {
public static void main(String[] args) {

int[] marks = new int[5];
marks[0] = 90;
marks[1] = 95;
marks[2] = 100;
marks[3] = 78;
marks[4] = 94;

int i =0;
while(i<5)
{
System.out.println(marks);
i = i+1;
}
}
}

output:
90
95
100
78
94

Notes4:


package Array;

public class Mark2 {
public static void main(String[] args) {

int[] marks = new int[5];
marks[0] = 90;
marks[1] = 95;
marks[2] = 100;
marks[3] = 78;
marks[4] = 94;

for(int i =0; i<marks.length; i = i+1)
{
System.out.println(marks);
}
}
}

Output:
90
95
100
78
94

Notes5:


package Array;

import java.util.Scanner;

public class Mark3 {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int[] marks = new int[5];
int i =0;
int total=0;
while(i<marks.length)
{
System.out.println("Enter Mark:");
marks = scanner.nextInt();
total=total+marks;
i+=1 ;
}
System.out.println(total);
}
}

Output:
Enter Mark:
80
Enter Mark:
50
Enter Mark:
89
Enter Mark:
90
Enter Mark:
86
395

Notes6:


package Array;

public class Mark4 {
public static void main(String[] args) {
int[] marks = {88,73, 82,88,95};
int total=0;
for(int i=0; i < marks.length; i++ )
{
total=total+marks;
}
System.out.println(total);
}

}

output:
426

Notes7:


package Array;

public class Mark5 {
public static void main(String[] args) {
int[] marks = {88,73, 82,88,95};
int max = 0;
if(88>max) max = 88;
if(73>max) max = 73;
if(82>max) max = 82;
if(88>max) max = 88;
if(95>max) max = 95;

System.out.println(max);

}
}

output:
95

Notes8:


package Array;

public class Mark6 {
public static void main(String[] args) {
int[] marks = {88,73, 82,88,95};
int max = 0;
if(marks[0]>max) max = marks[0];
if(marks[1]>max) max = marks[1];
if(marks[2]>max) max = marks[2];
if(marks[3]>max) max = marks[3];
if(marks[4]>max) max = marks[4];

System.out.println(max);

}
}

output:
95

Notes9:


package Array;

public class Mark7 {
public static void main(String[] args) {
int[] marks = {88,73, 82,88,95};
int max = 0;
for(int i=0; i<marks.length; i++)
{
if(marks>max)
max = marks;
}
System.out.println(max);
