How to Print an Array in Java

This updated guide examines How to Print an Array in Java and organizes the essential facts, background, and practical takeaways in clear American English.

Method 1

Using the toString Command

1. Setting the elements in your array. EnterString[] array = new String[] {"Elem1", "Elem2", "Elem3"}where "ElemX" are the individual elements in your array.
2. Use the standard library static method: Arrays.toString(array). This will give you a string representation of one dimensional arrays. In other words, because it is one dimensional, you can present the data in either rows or columns. This method will print the data in a row, or string.^{[1]XResearch source}
3. Run the program. Different compilers have different ways to accomplish this task. You may be able to go to "File" and then "Run." You may also have the option to simply click the "Run" icon in your toolbar. Your elements will be printed out in a string in the lower window of Java.

Method 2

Using the asList Command

1. Setting the elements in your array. EnterString[] array = new String[] {"Elem1", "Elem2", "Elem3"}where "ElemX" are the individual elements you want in your array.
2. Use the standard library static method: Arrays.asList()for one dimensional arrays that you want to print as a list.
3. Run the program. Different compilers have different ways to accomplish this task. You may be able to go to "File" and then "Run." You may also have the option to simply click the "Run" icon in your toolbar. Your elements will be printed out in a list or column in the lower window of Java.

Method 3

Printing Multidimensional Arrays

1. Setting the elements in your array. For a two-dimensional array, you will have both rows and columns that need to be printed out. Enterfor ( i = 0; i< rows; i++)for the rows andfor ( j = 0; j< columns; j++)for the columns.
2. Use the standard library static method: System.out.print(aryNumbers[i][j] + " " );followed bySystem.out.println( "" );to print arrays within arrays and multidimensional arrays as a line.^{[2]XResearch source}
