max function in java for array code example

Example 1: max in array java

// Initializing array of integers 
        Integer[] num = { 2, 4, 7, 5, 9 }; 
// using Collections.min() to find minimum element 
        // using only 1 line. 
        int min = Collections.min(Arrays.asList(num)); 
  
        // using Collections.max() to find maximum element 
        // using only 1 line. 
        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 ];

}
