6-2 Develop an algorithm - searching

Store data in a string or an array: int[], double[]

A. Count occurrence of a specific character in a string:

1. find the length of the string

2. loop through the string using for or while

3. inside the loop body, use charAt(i) to compare one character at a time

4. if found, increase the counter

5. else next loop iteration

B. Searching through a single string for digit 0-9:

1. set a flag: boolean found=false;

2. find the length of the string

3. loop through the string using for or while

4. inside the loop body, use charAt(i) to check if it is 0-9

5. if yes, found=true;

6. else next loop iteration

7. print found

C. Search for numbers of negative values(even/odd numbers, multiples of 7, prime numbers etc) in an array:

1. find the length of the array

2. loop through the array using for or while

3. inside the loop body, use array[i] to compare one at a time

4. if found, print it out;

5. else next loop iteration

D. Search through a String array:

1. use split() to create and print out a string array

2. find the length of the array

3. use for loop to go through each array element, which is a string

4. call a function to work/check on one string at a time

5. next loop iteration
