how to find max int in array code example

Example 1: 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 2: max element in array

int max;
max=INT_MIN;

for(int i=0;i<ar.length();i++){
	if(ar[i]>max){
    	max=ar[i];
    }
