Check out example codes for "finding min and max from given number in java". It will help you in understanding the concepts better.

Code Example 1

``````Scanner input = new Scanner(System.in);
// Minimum And Maximum
int count = 0;
int min = 0;
int max = 0;
boolean bugSolved = true;
/* or we can use :
int min = Integer.MAX_VALUE;
int max = Integer.MIN_VALUE;
*/

while (true){
int cnt = count++;
System.out.print("Enter Number #"+(cnt+1)+": ");
boolean isValid = input.hasNextInt();
if(isValid){
int num = input.nextInt();
/* if (bugSolved){
bugSolved = false;
min = num;
max = num;
}  # Just remove this condition and
boolean (bugSolved) at the top, if you use
int min = Integer.MAX_VALUE and int max =
Integer.MIN_VALUE */
if (num < min) {
min = num;
}else if (num > max){
max = num;
}
}else{
System.out.println("Invalid input..");
break;
}
input.nextLine();
}
System.out.println("Min Number : " + min);
System.out.println("Max Number : " + max);``````

Code Example 2

``````import java.util.Random;

public class Main {

public static void main(String[] args) {
int a[] = new int [100];
Random rnd = new Random ();

for (int i = 0; i< a.length; i++) {
a[i] = rnd.nextInt(99-0)+0;
System.out.println(a[i]);
}

int max = 0;

for (int i = 0; i < a.length; i++) {
a[i] = max;

for (int j = i+1; j<a.length; j++) {
if (a[j] > max) {
max = a[j];
}

}
}

System.out.println("Max element: " + max);
}
}``````

Code Example 3

``````public static double arrayMax(double[] arr) {
double max = Double.NEGATIVE_INFINITY;

for(double cur: arr)
max = Math.max(max, cur);

return max;
}``````

Code Example 4

``````import java.util.Arrays;

public class apples {

public static void main(String[] args) {
int a[] = {2,5,3,7,8};
Arrays.sort(a);

int min =a[0];
System.out.println(min);
int max= a[a.length-1];
System.out.println(max);

}

}``````

Code Example 5

``````private static int findMin(int[] array) {
int min = array[0];
for(int i=1;i<array.length;i++) {
if(min > array[i]) {
min = array[i];
}
}
return min;
}``````
