Uyenza njani ifayile yexeshana kwiJava
Kukho amaxesha apho kufuneka senze iifayile zexeshana kubhabho ukugcina ulwazi kunye nokuzicima emva koko.
KwiJava, sinokusebenzisa Files.createTempFile() iindlela zokwenza iifayile zethutyana.
Yenza Iifayile Zethutyana
Lo mzekelo ulandelayo usebenzisa Files.createTempFile(prefix, suffix) ukwenza ifayile yexeshana.
import java.io.IOException; import java.nio.file.Files; import java.nio.file.Path; public class CreateTempFile {
public static void main(String[] args) {
try {
// Create a temporary file
Path tempFile = Files.createTempFile('temp-', '.txt');
System.out.println('Temp file : ' + temp);
} catch (IOException e) {
e.printStackTrace();
}
} } Iziphumo:
Temp file : /var/folders/nyckvw0000gr/T/temp-2129139085984899264.txt Apha, 'temp-' isimaphambili kunye '.text' sisimamva.
Phawula:Ngokuzenzekelayo iJava yenza ifayile yexeshana kulawulo lwethutyana. Singasifumana isikhombisi sethutyana ngokwenza
System.getProperty('java.io.tmpdir')Ukuba isimamva asisebenzi, ifayile yethutyana yenziwe nge .tmp ulwandiso.
Umzekelo:
Path tempFile = Files.createTempFile('prefix-', null); System.out.println('Temp file : ' + tempFile); // Temp file : /var/folders/nyckvw0000gr/T/prefix-17184288103181464441.tmp Kananjalo ukuba isimamva asibonelelwanga ngefayile ye-temp yenziwe ngaphandle kolwandiso:
Path tempFile = Files.createTempFile(null, ''); System.out.println('Temp file : ' + tempFile); // Temp file : /var/folders/nyckvw0000gr/T/1874152090427250275 Yenza Ifayile yeTempsi kulawulo oluchaziweyo
Endaweni yokuvumela iJava ukuba ikhethe isikhombisi, singasixelela ukuba senze ifayile yexeshana phi.
Umzekelo:
import java.io.IOException; import java.nio.file.Files; import java.nio.file.Path; import java.nio.file.Paths; public class CreateTempFile {
public static void main(String[] args) {
try {
Path path = Paths.get('target/tmp/');
// Create a temporary file in the specified directory.
Path tempFile = Files.createTempFile(path, null, '.log');
System.out.println('Temp file : ' + temp);
} catch (IOException e) {
e.printStackTrace();
}
} } Phawula:Isikhokelo esichaziweyo kufuneka sibekhona kwifayile yexeshana ukuba ibhalelwe.Yenza iFayile yeTempsi kwaye ubhale kuyo
Umzekelo olandelayo wekhowudi wenza ifayile yethutyana emva koko ubhale umbhalo othile kuyo:
import java.io.IOException; import java.nio.charset.StandardCharsets; import java.nio.file.Files; import java.nio.file.Path; import java.nio.file.Paths; public class CreateTempFile {
public static void main(String[] args) {
try {
Path path = Paths.get('target/tmp/');
// Create an temporary file in a specified directory.
Path tempFile = Files.createTempFile(path, null, '.log');
System.out.println('Temp file : ' + tempFile);
// write a line
Files.write(tempFile, 'Hello From Temp File
'.getBytes(StandardCharsets.UTF_8));
} catch (IOException e) {
e.printStackTrace();
}
} } Ukuqhubeka kokufunda:
