runtime error - Please clarify the issue in the java code below - 


  आयात करें java.lang.Process; Import java.io * *; Import java.io.InputStream; आयात java.io.IOException; सार्वजनिक वर्ग prgms {public static void main (स्ट्रिंग [] args) {try {/ /} बिना किसी आदेश के आदेश कमांड स्ट्रिंग कमांड = "जावा जावासिंपलडेटाफ़ॉर्मेट उदाहरण"; प्रक्रिया बच्चे = Runtime.getRuntime ()। Exec (कमांड); // एक तर्क के साथ एक आदेश निष्पादित करें / / कमांड = "जावा जावास्ट्रिंगबफ़रअपेपेंडैक्स"; // बच्चा = रनटाइम.गेटरीटाइम ()। Exec (कमांड); } पकड़ (IOException ई) {} InputStream में = child.getInputStream (); Int c; जबकि ((c = in.read ())! = -1) {प्रक्रिया ((चार) सी); } In.close (); }}

मैंने इस तरह से संशोधित किया है ... लेकिन निम्न त्रुटि उत्पन्न होती है, 

  prgms.java:17: प्रतीक प्रतीक नहीं मिल सकता है: चर बच्चे स्थान: वर्ग prgms InputStream = child.getInputStream () में; ^ Prgms.java 20: प्रतीक प्रतीक नहीं मिल सकता है: विधि प्रक्रिया (चार) स्थान: वर्ग prgms प्रक्रिया ((चार) सी); ^ 2 त्रुटियां

आप वास्तव में लौटाए गए धाराओं की अनदेखी कर रहे हैं। < / P>

यह एक लंबी कहानी बनने वाली है, इसलिए यहां केवल एक लिंक है: सभी चार पृष्ठों को पढ़ें।

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT?

But I do not think the code is capable of changing the color of each variable declared....
