Java Program to count the total number of characters in a string

In this program, we need to count the number of characters present in the string:

The best of both worlds

To count the number of characters present in the string, we will iterate through the string and count the characters. In above example, total numbers of characters present in the string are 19.

For programming, follow the algorithm given below:

Algorithm

• STEP 1: START
• STEP 2: DEFINE String string = "The best of both worlds".
• STEP 3: SET count =0.
• STEP 4: SET i=0. REPEAT STEP 5 to STEP 6 UNTIL i<string.length
• STEP 5: IF (string.charAt(i)!= ' ') then count =count +1.
• STEP 6: i=i+1
• STEP 7: PRINT count.
• STEP 8: END

Program:

Output:

Total number of characters in a string: 19
