From ec2976f6fa8a6747b0a9e7b2d85466ed863dfd9a Mon Sep 17 00:00:00 2001 From: jaemin7666 Date: Sat, 6 Jun 2020 21:15:40 +0900 Subject: [PATCH] Refactoring operation name : rename Refactoring object : QrCodeGeneratorDemo.java Reason : QrCode qr, List segs is too simple to express meaning. So,rename qr to qrCode and segs to segments. --- .settings/org.eclipse.core.resources.prefs | 2 + .../nayuki/qrcodegen/QrCodeGeneratorDemo.java | 88 +++++++++---------- 2 files changed, 46 insertions(+), 44 deletions(-) create mode 100644 .settings/org.eclipse.core.resources.prefs diff --git a/.settings/org.eclipse.core.resources.prefs b/.settings/org.eclipse.core.resources.prefs new file mode 100644 index 0000000..e5bd3bf --- /dev/null +++ b/.settings/org.eclipse.core.resources.prefs @@ -0,0 +1,2 @@ +eclipse.preferences.version=1 +encoding//java/src/main/java/io/nayuki/qrcodegen/QrCodeGeneratorDemo.java=UTF-8 diff --git a/java/src/main/java/io/nayuki/qrcodegen/QrCodeGeneratorDemo.java b/java/src/main/java/io/nayuki/qrcodegen/QrCodeGeneratorDemo.java index 3c50bda..a001ff9 100644 --- a/java/src/main/java/io/nayuki/qrcodegen/QrCodeGeneratorDemo.java +++ b/java/src/main/java/io/nayuki/qrcodegen/QrCodeGeneratorDemo.java @@ -70,22 +70,22 @@ public final class QrCodeGeneratorDemo { // Creates a variety of QR Codes that exercise different features of the library, and writes each one to file. private static void doVarietyDemo() throws IOException { - QrCode qr;
