How to Write an Array of Strings to the Output Console in Java

We can write an array of strings to the output console in Java by using loops or built-in utility methods. The following are the ways to write an array of strings to the output console.

• Using for-loop

• Using Arrays.toString()

• Nested Array

A for loop iterates through the array and prints each element to the console. It repeats a code block for a specified number of iterations.

The following is the syntax for using for loop

for (statement 1; statement 2; statement 3) {
  // code block to be executed
}

The following example demonstrates writing elements of an array to the output console through looping

public class Welcome {
   public static void main(String[] args) {
      String[] greeting = new String[3];
      greeting[0] = "This is the greeting";
      greeting[1] = "for all the readers from";
      greeting[2] = "Java Source .";
      
      for (int i = 0; i < greeting.length; i++){
         System.out.println(greeting[i]);
      }
   }
}

This is the greeting

The java.util.Arrays.toString(int[]) method provides a string representation of the elements in the specified int array. This representation includes the array's elements enclosed in square brackets ("[]"), with adjacent elements separated by ", " (a comma and a space).

The following example demonstrates writing elements of an array to the output console using Arrays.toString()

import java.util.Arrays;

public class HelloWorld {
   public static void main(String[] args) {
      String[] arr = new String[] {"Tutorials", "Point", ".com"}; 
      System.out.println(Arrays.toString(arr));
   }
}

[Tutorials, Point, .com]    .

The Arrays.deepToString() method is used for nested arrays (arrays within arrays). It returns a string representation of multidimensional arrays, ensuring that each sub-array is properly represented, with brackets around each array and all elements displayed.

The following example demonstrates writing elements of an array to the output using Arrays.deepToString() method

import java.util.Arrays;

public class HelloWorld {
   public static void main(String[] args) {
      String[][] deepArr = new String[][] {{"Sai", "Gopal"}, {"Pallavi", "Priya"}};
      System.out.println(Arrays.toString(deepArr));
      System.out.println(Arrays.deepToString(deepArr));
   }
}
