Java Program to write int array to a file
Here’s our file −
FileWriter writer = new FileWriter("E:/demo.txt");Now, consider an Integer array −
Integer arr[] = { 10, 20, 30, 40, 50 };Write the above array to the file “demo.txt” −
int len = arr.length;
for (int i = 0; i < len; i++) {
writer.write(arr[i] + "\t" + "");
}The following is an example. Here, our file is “E:/input.txt” −
Example
import java.io.FileWriter;
public class Demo {
public static void main(String[] argv) throws Exception {
FileWriter writer = new FileWriter("E:/input.txt");
Integer arr[] = { 10, 20, 30, 40, 50 };
int len = arr.length;
for (int i = 0; i < len; i++) {
writer.write(arr[i] + "\t"+ "");
}
writer.close();
}
}The output is as follows i.e. the text in the file is −
