What I am trying to do is have it take a java file that look like this
public class test1 {
public static void main ( string[] args ) {
System.out.println( "This is Test 1." );
}
}
And it is suppose to output a text file with the proper spacing and indents. So far I can get the correct indenting for the first the lines. But I am having trouble with my second for loop that prints the spaces for the ending brackets. The ending brackets are prints outward like the first 3 lines instead of inward. Sorry if my variables are confusing.
Here is my code so far
public class JavaJustifier {
public static void main( String[] args )
throws FileNotFoundException {
for( int i = 1; i < 6; i++ ) {
justifyJava( "Test" + i + ".java",
"Justified" + i + ".txt",
4 );
}
}
public static void justifyJava( String inputFileName,
String outputFileName,
int tabSize )
throws FileNotFoundException {
int counter = 0;
int counter2 = 0;
int blah = 0;
File f = new File(inputFileName);
File p = new File(outputFileName);
if (p.exists())
p.delete();
Scanner input = new Scanner (f);
PrintStream name = new PrintStream(new File(outputFileName));
while (input.hasNextLine()) {
String line = input.nextLine();
Scanner lineScan = new Scanner(line);
if (line.contains("{") == true) {
name.print("{\r\n");
counter++;
for (int i = 1; i <= counter; i++) {
for (int j = 0; j <= tabSize; j++) {
name.print(" ");
}
}
System.out.println(counter);
} else if (line.contains("}") == true) {
name.print("\r\n");
counter--;
for (int x = 1; x <= counter; x++) {
for (int y = 1; y <= tabSize; y++) {
name.print(" ");
}
}
name.print("}");
System.out.println(counter);
} else {
name.print(line);
}
}
}
What it gives me is
public class Test1
{
public static void main( String[] args )
{
System.out.println( "This is Test 1." );
}
}
What I desire is this
public class Test1
{
public static void main( String[] args )
{
System.out.println( "This is Test 1." );
}
}
Okay, I've refactored a few things (and it was necessary) but it works exactly as you expect it to (AFAIK!).
Here's the code:
public class JavaJustifier {
static int counter = 0;
static int tabSize = 4;
public static void main(String[] args) throws FileNotFoundException {
justifyJava("Test1.java", "Justified1.txt");
}
private static void processLine(PrintStream name, String line) {
if (line.contains("{")) {
String preText = line.substring(0, line.indexOf("{"));
String postText = line.substring(line.indexOf("{") + 1)
.replaceAll("\\n", "").replaceAll("\\r\\n", "");
printSpaces(name);
name.println(preText);
printSpaces(name);
name.println("{");
counter++;
processLine(name, postText);
} else if (line.contains("}")) {
String preText = line.substring(0, line.indexOf("}"));
String postText = line.substring(line.indexOf("}") + 1)
.replaceAll("\\n", "").replaceAll("\\r\\n", "");
name.println(preText);
counter--;
printSpaces(name);
name.println("}");
processLine(name, postText);
} else {
if (!line.equals("\r\n") && line.length() != 0) {
printSpaces(name);
name.print(line);
}
}
}
private static void printSpaces(PrintStream p) {
for (int i = 1; i <= counter; i++) {
for (int j = 0; j <= tabSize; j++) {
p.print(" ");
}
}
}
public static void justifyJava(String inputFileName, String outputFileName)
throws FileNotFoundException {
File f = new File(inputFileName);
File p = new File(outputFileName);
if (p.exists())
p.delete();
Scanner input = new Scanner(f);
PrintStream name = new PrintStream(new File(outputFileName));
while (input.hasNextLine()) {
String line = input.nextLine().trim();
processLine(name, line);
}
}
}
