Using Google Guava to format Strings
guava, java, pad, string
Solution
`String.format`
You can simply use String.format() instead of Guava. It follows the C printf syntax described here. I think that it meets your needs.
String aVeryLongString="aaabbbcccdddeeefffggghh";
String aShortString="abc";
String anotherString="helloWorld";
String formattedString=String.format("%5.5s,%5.5s,%5.5s",aVeryLongString,aShortString,anotherString);
System.out.println(formattedString);
Output :
aaabb, abc,hello
As you can see, the long String was cut and the short String was padded.
Problem
I am using Google guava to format Strings and write them to a text file using BufferedWriter ``` import com.google.common.base.Strings; import java.io.*; public class Test { public static void main(String[] args) { File f = new File("MyFile.txt"); String firstName = "STANLEY"; String secondName = "GATUNGO"; String thirdname = "MUNGAI"; String location = "NAIROBI"; String school = "STAREHE BOYS CENTRE"; String yob= "1970"; String marital = "MARIED"; String texture = "LIGHT"; try { BufferedWriter bw = new BufferedWriter(new FileWriter(f)); if (!f.exists()) { f.createNewFile(); } bw.write(Strings.padStart(firstName, 0, ' ')); bw.write(Strings.padStart(secondName, 20, ' ')); bw.write(Strings.padStart(thirdname, 20, ' ')); bw.write(Strings.padStart(location, 20, ' ')); bw.newLine(); bw.write(Strings.padStart(school, 0, ' ')); bw.write(Strings.padStart(yob, 20, ' ')); bw.write(Strings.padStart(marital, 20, ' ')); bw.write(Strings.padStart(texture, 20, ' ')); bw.close(); } catch (Exception asd) { System.out.println(asd); } } } ``` My Output is I need the output to be I am receiving the Strings from the database and the Database And the Hardcoding Above is Just an example, I need to write the Strings Such that the Length of the First String doe not affect the Beginging Position of the second String. I need to write them in Column Manner all beginging at the same Position using Google Guava. I will Appreciate examples also.
