Question

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.

Answer 1

Answer:

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.
