how to get the width and height of a string in java
String text = "Hello World";
Font font = new Font("Arial", Font.PLAIN, 12);
FontRenderContext frc = new FontRenderContext(new AffineTransform(), true, true);
int textwidth = (int)(font.getStringBounds(text, frc).getWidth());
int textheight = (int)(font.getStringBounds(text, frc).getHeight());length of string java
public class Sample_String {
public static void main(String[] args) {
//declare the String as an object S1 S2
String S1 = "Hello Java String Method";
String S2 = "RockStar";
//length() method of String returns the length of a String S1.
int length = S1.length();
System.out.println("Length of a String is: " + length);
//8 Length of a String RockStar
System.out.println("Length of a String is: " + S2.length());
}
}String length() method in java
// String length() method example
public class StringLengthJava
{
public static void main(String[] args)
{
String str1 = "flowerbrackets";
String str2 = "helloworld";
System.out.println("string length : " + str1.length());
System.out.println("string length : " + str2.length());
}
}length and length() method in java
length() : In String class we have length() method which is used
to return the number of characters in string.
Ex : String str = “Hello World”;
System.out.println(str.length());
Str.length() will return 11 characters including space.
length : we have length instance variable in arrays which will
return the number of values or objects in array.
For example :
String days[]={” Sun”,”Mon”,”wed”,”thu”,”fri”,”sat”};
Will return 6 since the number of values in days array is 6length method in java
public class LengthMethodDemo {
public static void main(String[] args) {
//declaring variables string1 & string2
String string1 = "Java";
String string2 = "Java Code";
// Java
//count from left 1234 --> so length would be 4
int lengthOfString1 = string1.length(); // 4
// Java Code
//count from left 123456789 --> so length would be 9
int lengthOfString2 = string2.length(); // 9
System.out.println("Length of String1 is : "+lengthOfString1);
System.out.println("Length of String2 is : "+lengthOfString2);
String string3="";
System.out.println(string3.length()); //0
String string4=null;
System.out.println(string4.length()); //It will give NullPointerException
}
