I need help Developing a Java program that will accept user input, until a strong password is entered. After each user attempt at inputting a password display one of the following messages • Invalid • Low Security Level • Medium Security Level • Strong Security Level Continue prompting the user until a strong password is entered. Use the criteria listed below to determine password security level. Low - Each password must have at least 5 characters. This is the default security level. Medium - Each password must have at least 6 characters and meet the following requirements: • Includes numbers and mixed case letters High - Each password must have at least 8 characters and meet the following requirements: • Includes numbers and mixed case letters • Includes a special character that is not a letter or number Invalid - doesn't meet minimum requirements of the low (default) security level. I have code but I keep getting errors that I don't know how to fix. Can you help edit them?
I need help Developing a Java program that will accept user input, until a strong password is entered. After each user attempt at inputting a password display one of the following messages
• Invalid
• Low Security Level
• Medium Security Level
• Strong Security Level
Continue prompting the user until a strong password is entered. Use the criteria listed below to
determine password security level.
Low - Each password must have at least 5 characters. This is the default security level.
Medium - Each password must have at least 6 characters and meet the following requirements:
• Includes numbers and mixed case letters
High - Each password must have at least 8 characters and meet the following requirements:
• Includes numbers and mixed case letters
• Includes a special character that is not a letter or number
Invalid - doesn't meet minimum requirements of the low (default) security level.
I have code but I keep getting errors that I don't know how to fix. Can you help edit them?
