1) Write method, extractEvens, which accepts an array of int and returns an array containing only the even integers found in the formal parameter. The returned array should be the right- size, meaning that all of its elements are used to store an even int found in the parameter. This means that the returned array may have anywhere from zero to n elements, where n is the length of the formal parameter array.

- Julius Caesar is known as the first person to document themilitary use of encryption. Caesar’s cipher was a cipher that created asecret message by shifting a little by certain number of positions. Forexample, for a shift value of 3, the letter ’A’ would be replaced by aletter ’D’. Write an algorithm that displays a secret message given amessage (assume all in caps) and a shift valueHelp me solve this problem!: Method Skeletons and a Loop Roundup Practice these steps again and then solve the set of loop problems.
