如何输入字符串内容：encoded =“ Hello”; 在java中？

Question

How to type String content:encoded = "Hello"; in java ? Eclipse keep telling me syntax error on tokens delete these tokens ?

setDescription(String content:encoded) {
    _description = content:encoded;
}

Answer 1

Because content:encoded is a syntax error. Name in java only accept letters numbers $ and "_". The rule might allow some other characters but it should be pretty much it. Also a variable cannot start with a number.

To be clear, remove the : from the variable name because : is illegal in a name and might have an other meaning in the language.

Quote from the article below:

1. Variable names are case-sensitive. A variable's name can be any legal identifier — an unlimited-length sequence of Unicode letters and digits, beginning with a letter, the dollar sign $ , or the underscore character _ . The convention, however, is to always begin your variable names with a letter, not $ or _ . Additionally, the dollar sign character, by convention, is never used at all. You may find some situations where auto-generated names will contain the dollar sign, but your variable names should always avoid using it. A similar convention exists for the underscore character; while it's technically legal to begin your variable's name with _ , this practice is discouraged. White space is not permitted.
2. Subsequent characters may be letters, digits, dollar signs, or underscore characters.

Answer 2

if you are creating method setDescription then it whould be:

public void setDescription(String content_encoded) {
    _description = content_encoded;
}

Here

1. public is modifier
2. void is return type
3. setDescription is method name
4. String is parameter type
5. content_encoded is Variable that is holding string value.
