The error you are getting is because your generic is using improper bounding. Change your method declaration to: public static <T extends IFoo2> T convert(IFoo1 foo1, Class<T> clz) { T foo2 = clz.newInstance(); …. return foo2; } There is another type of bounding you may have been thinking of. I recommend reading this SO question: … Read more
!read.eof() only checks for end of file, not errors reading the file, such as a networked mounted file system not being ready, disk error, or lack of permission to read the file. You should check for all failures, with while(read) which has an overloaded operator to check everything for you. So, if the file fails, … Read more
Lets break pow(payMent = loanAmount * monthlyIntrest / (1 – (1 + monthlyIntrest),-loanDuration)); down a bit. payMent = loanAmount * monthlyIntrest / (1 – (1 + monthlyIntrest),-loanDuration) is one argument. The comma that should split it into two arguments is inside the brackets. Likely you meant payMent = loanAmount * monthlyIntrest / (1 – (1 … Read more

You can do this, the only difference being the condition used is the length of the array instead of an individual value. n = len(arr) for i in range(n): for j in range(n-i-1): if len(arr[j]) > len(arr[j+1]): arr[j], arr[j+1] = arr[j+1], arr[j] 2 solved How do i sort a 2D array or multiple arrays by … Read more
Notice that the names are separated by a colon(:) so add : in split() to split them and store them in multiple variables: with open(“filename.txt”) as f: for line in f : word1,word2,word3 = line.split(“:”) print(word1) print(word2) print(word3) 0 solved Open txt file in python
You are returning from the function before calling remove.

The Bash shell searches the directories listed in the PATH variable in both shellscript and . shellscript cases. The main difference is that when using . (or equivalently source) to start a script, a new shell process is not created for interpreting the script. This is sometimes useful because it allows the script to define … Read more
You have functions such as def car1 (x1,y1): gameDisplay.blit(car1IMG,(x1,y1)) which will blit the global image car1IMG. Then in your game_loop function you write car1IMG = pygame.image.load(‘textures\car1.png’) which creates a local variable with the same name. So everything in your game_loop function will always use the local variable instead of the global, unless you specify that … Read more
