finding 19th largest number from array in java code example

Example 1: java how to find the largest number in an arraylist

List<Integer> myList = new ArrayList<>();

for(int i = 0; i < 10; i++){
    myList.add(i);
}
//gets highest number in the list
int highestNumber = Collections.max(myList);

System.out.Println(highestNumber);

//output: 9

Example 2: find the maximum number from an int Array

---without sort method---
public static int maxValue( int[]  n ) {

int max = Integer.MIN_VALUE;

for(int each: n)

if(each > max)

max = each;

 
return max;
  
---with sort method---
public static int maxValue( int[]  n ) {

Arrays.sort( n );

return  n [ n.lenth-1 ];

}

Example 3: java find largest number in list

int max = (The provided List).stream().max((i1,i2)->(i1>i2)?1:(i1<i2)-1:0).get();
