Java.lang.NoClassDefFoundError problem Solved

Exception in thread "main" java.lang.NoClassDefFoundError

Sometimes when we try to execute java program we got error message like "Exception in thread "main" java.lang.NoClassDefFoundError".

But this is not a major issue. It just a common human mistake.

You might have compiled java program with small letter-case followed by .java extension but actually file name is in the capital letters. The program will compile without any error but do not.
Note: Check filename before you compile java program ( Java is case Sensitive).
for example:
In my case: filename is MyClass.java
I compiled it as javac myClass.java
Compiled successfully
But do not execute... give error message like this

Solution: Compile it as javac Myclass.java
Java is very case sensitive language.

Linear search & Binary search using Template

Write a program to search an element from a list. Give user the option to perform Linear or Binary search. Use Template functions. #include<iostream> using namespace std; template <class T> void Lsearch(T *a, T item, int n) { int z=0; for(int i=0;i<n;i++) { if(a[i]== item) { z=1; cout<<"\n Item found at position = "<<i+1<<"\n\n"; } else if(z!=1) { z=0; } } if(z==0) cout<<"\n Item not found in the list\n\n"; } template <class T> void Bsearch(T *a, T item, int n) { int beg=0,end=n-1; int mid=beg+end/2; while((a[mid]!=item) && (n>0)) { if(item>a[mid]) beg=mid; else end=mid; mid=(beg+end)/2; n--; } if(a[mid]==item) cout<<"\n Item found at position = "<<mid+1<<"\n\n"; else cout<<"\n Item not found in the list\n\n"; } void main() { int iarr[10] = {2,42,56,86,87,99,323,546,767,886};
