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);         }     } }

i need output

desired output

i receiving strings database , database , hardcoding above example, need write strings such length of first string doe not affect beginging position of second string. need write them in column manner beginging @ same position using google guava. appreciate examples also.

string.format

you can use string.format() instead of guava. follows c printf syntax described here. think meets 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 can see, long string cut , short string padded.
