arrays in methods java code example

Example 1: Arrays in java

// Accessing array elements using for loop
public class AccessingArrayElements
{
   public static void main(String[] args)
   {
      int[] arrNum = {25, 23, 15, 20, 24};
      for(int a = 0; a < arrNum.length; a++)
      {
         System.out.println(arrNum[a]);
      }
   }
}

Example 2: arrays in java

For example: int[ ] num = new int[6];
public class AccessingArrayElements
{
   public static void main(String[] args)
   {
      int[] arrNum = {25, 23, 15, 20, 24};
      for(int a = 0; a < arrNum.length; a++)
      {
         System.out.println(arrNum[a]);
      }
   }
}

Example 3: arrays in java

int[] intArray = new int[20];
String[] cars = {"Volvo", "BMW", "Ford", "Mazda"};

Example 4: array methods in java

String[] aArray = new String[5];
String[] bArray = {"a","b","c", "d", "e"};
String[] cArray = new String[]{"a","b","c","d","e"};

Example 5: java Arrays method

int[] intArray = { 1, 2, 3, 4, 5 };
String intArrayString = Arrays.toString(intArray);
 
// print directly will print reference value
System.out.println(intArray);
// [I@7150bd4d
 
System.out.println(intArrayString);
// [1, 2, 3, 4, 5]
