Assume that name is a variable of type String that has been assigned a value. Write an expression whose value is the first character of the value of name.

name. charAt (0);

Explanation:

Given: 'name' is a variable of type String that has been assigned a value.

To determine: an expression whose value is the first character of the value of name.

Let us assume nae is assigned the value "test". So our expression should return the first character, that is 't'.

In order to do this, we can use the charAt method of String object.

String name="test";

char c = name. charAt (0);

Here 0 corresponds to the index of the character we are interested in.
