importjava.util.Arrays;publicclassPrintingAnArray{publicstaticvoidmain(String args[]){intArray[]={1,2,3,4,5};System.out.println(Arrays.toString(Array));}} Output: [1, 2, 3, 4, 5] Use thestream().forEach()Method to Print an Array in Java ...
In this code, you use theprintln()method to print the second element of thepasswordarray. (For more on theSystem.out.printlnstatement, check out our tutorialHow To Write Your First Program in Java.) The second element has an index of1because array elements are numbered starting at 0, as ...
System.out.println(ArrayUtils.toString(arrayOfArray)); 3. Conclusion This short Java tutorial taught us how to print anarray in Javawith and without loops. We learned to print a simple array usingArrays.toString()and print multidimensional arrays usingArrays.deepToString(). Note that it does not...
TheArrays.sort()method is another way to sort arrays in Java. It works similarly toCollections.sort(), but it’s used for arrays instead of lists. int[]numbers={3,2,1};Arrays.sort(numbers);System.out.println(Arrays.toString(numbers));// Output:// [1, 2, 3] Java Copy In this ex...
importjava.util.Arrays;publicclassCopyArray{publicstaticvoidmain(String[]args){int[]array1=newint[]{2,4,6,8,10};int[]array2=Arrays.copyOf(array1,array1.length);for(inti=0;i<array2.length;i++){System.out.println("array2 position "+i+": "+array2[i]);}}} ...
In this article, we will take a look on to How to return Empty array in java. We will look at different ways to achieve this with demonstrated working examples in detail. At first, let us have a brief look into Arrays in java and what exactly is an Empty Array and how it is differ...
ObjectArrays.concat(): concatenates twoobjecttype arrays. String[]resultObj=ObjectArrays.concat(strArray1,strArray2,String.class);int[]result=Ints.concat(intArray1,intArray2); 6. Conclusion In this tutorial, we learned tomerge two arrays in Java. We learned to use the native Java APIs as...
Inside the code block, theSystem.out.println("x is " + x--);statement on line 3 prints the current value ofxusing theprintln()method. (For more on theSystem.out.printlnstatement, check out our tutorialHow To Write Your First Program in Java.) Inside the argument forprintln(),xis post...

In Java, arrays can be declared in one of two ways; the major difference between each method is that one takes up significantly more space than the other when it comes time to define its variables. Declaring an Array Example publicclassArrays{ ...
