java max of array code example
Example 1: max in array java
Integer[] num = { 2, 4, 7, 5, 9 };
int min = Collections.min(Arrays.asList(num));
int max = Collections.max(Arrays.asList(num));
Example 2: how to get the max value of an array java
public static double arrayMax(double[] arr) {
double max = Double.NEGATIVE_INFINITY;
for(double cur: arr)
max = Math.max(max, cur);
return max;
}
Example 3: java max array
public static String max(String[] arr) {
String result = arr[0];
for (int i = 1; i < arr.length; ++i) {
if (result.compareTo(arr[i]) < 0) result = arr[i];
}
return result;
}
Example 4: java max array
public static double max(double[] arr) {
double result = arr[0];
for (int i = 1; i < arr.length; ++i) {
if (result < arr[i]) result = arr[i];
}
return result;
}
Example 5: java max array
public static double max(double[] arr) {
double result = Double.NEGATIVE_INFINITY;
for (int i = 0; i < arr.length; ++i) {
if (result < arr[i]) result = arr[i];
}
return result;
}
Example 6: 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 ];
}
