Conversion between hexadecimal in java and java hexadecimal conversion

Conversion between hexadecimal in java and java hexadecimal conversion

// Convert decimal to other hexadecimal

Integer. toHexString (10); // converts 10 to hexadecimal format, and returns the string type.

Integer. toOctalString (10); // convert 10 to octal and return the string type.

Integer. toBinaryString (10); // convert 10 to binary and return the string type.

 

// Convert other hexadecimal values to decimal values

 

// Convert hexadecimal to decimal, for example, 0 xFFFF

Integer. valueOf ("FFFF", 16). toString (); // the valueOf () method returns the Integer type, and the toString () method is called to return the string.

Integer. parseInt ("FFFF", 16); // returns the basic int data type.

Integer. toString (0 xFFFF); // This method can be used to directly input the basic data type that represents a hexadecimal number. The method returns a string.

 

// Convert octal to decimal, for example, 017

Integer. valueOf ("17", 8). toString (); // the valueOf () method returns the Integer type. Call toString () to return the string.

Integer. parseInt ("17", 8); // returns the basic int data type.

Integer. toString (017); // This method can be used to directly input the basic data type representing the octal number. The method returns a string.

 

// Convert binary to decimal, for example: 0101

Integer. valueOf ("0101", 2). toString (); // the valueOf () method returns the Integer type. Call toString () to return the string.

Integer. parseInt ("0101", 2); // returns the basic int data type.

 

// For the conversion between binary, octal, and hexadecimal, You can first convert it to decimal, and convert it in the corresponding method of convert it into multi-hexadecimal

// For example, convert hexadecimal 0xFF to binary

Integer. toBinaryString (Integer. valueOf ("FF", 16 ));

// Or

Integer. toBinaryString (Integer. parseInt ("FF", 16 ));

 

// For the input string that represents the hexadecimal format, you must first intercept the number substring and convert it to decimal using the valueOf () or parseInt () method.

// For example, enter 0xFF

String s = "0xFF ";

Integer. valueOf (s. subString (2, s. length (), 16 );

 

// For the valueOf method, it can be used for packing basic data types and conversion from multi-hexadecimal to decimal.
