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 ];

Integer[] num = { 2, 4, 7, 5, 9 };
// using Collections.min() to find minimum element

// using Collections.max() to find maximum element
// using only 1 line.
int max1 = Collections.max(Arrays.asList(num));
System.out.println(min1); // 2
